GS Tape Machines

[1] To remove the fix screw which tighten “Header” and Pipe (of Air shaft).
[2] To remove the “Nipple”.
[3] To drill a hole and tapping thread on shaft head.
[4] To connect together the Header, Bush,Slider and Pull rod.
[5] To put a screw on each expansion strip then use a stationer clip to hold the Strip, keep all strip on outside of Aluminum tube.
[6] To hanging and hold the shaft vertically, then use the slider to hammer the pull rod remove the “Header” and rubber tube together.
[7] To change a new tube on “Header” and another end (of rubber tube) put into the pipe.
[8] To put back the “Header” and the holes of “Header” and pipe must be matched, thus the screw can be fixed.
[9] After completely tighten the screw then put back the Nipple, and the change job is completed.

How to set the required length:

[1] Press M, then the screen show “S E t.2” & digit “000000”
[2] Press  then the digit will be flashing, press more times to select the required digit. The same for and so on.
[3] These digit is mention “sensed points” of ratchet.

[4] The OD of “measured” roller is 106 mm, thus the circle is 333 mm, or may calculate 3 cycles is 1 meter. If only 1 screw on the ratchet, i.e. 1 sensed point is 1 circle. If 2 screws on the ratchet, i.e. 2 sensed points is 1 circle.
[5] Press M again, then the screen show “S E t.2” & digit “000000”
[6] “S E t.2” is setting for total required length.
[7] Press M again, then the screen show “S E t.1” & digit “000000”
[8] “S E t.1” is setting for starting slow down the running speed, usually this digit may be set 30 cycles less than “S E t.2”.
[9] For example: produce 50 meters roll, then setting digit of “S E t.2” at “150” and “S E t.1” at “120”. Do try one operation then fine adjustment the final digits.

 

Before operate this counter, please check the parameters in this counter:

[1] Push E & M key
[2] the screen will show “JS” or JL (should be “JS”)
[3] Continuously push the M key, the screen will show “OP-t”, “H.R.C.E.”, “d p”, “ P S C”, then “HS” or “LS” (should be “HS”)

If the setting is correct, then use this counter.

 

In fact, to produce a adhesive tape is very easy.
Basically, you just need 2 raw materials for making a tape – substrates (film) and adhesives.
Thus, you may produce any kinds of tape, if you can get these 2 materials.

There are some popular tapes already be used in our living, as: OPP packing tape, OPP stationery tape, PVC electric insulating tape, tissue double side tape, foam tape, PE protection tape, label stock, cloth tape and paper masking tape, …etc.

Which kinds film (substrates) is available at your place ? Polypropylene (PP), Polyethylene (PE), Polyester (PET), poly vinyl chloride (PVC), Copper foil and Aluminum foil, etc. Thus above tapes can be produced at your place.

What kinds of adhesives which used for above tapes? Popularly only 2 kinds – water based Acrylic adhesives and solvent based Acrylic adhesives. Therefore if you could get or import these adhesives then you can produce above tapes.

 

To use a higher solid content of adhesives then the production speed will be increased, is it true ?

The answer is not really.

Popularly, the water based Acrylic adhesives manufacturer may offer you the solid content between 50-65%. It seems, if used higher solid content, thus water contents will be less, the production may be increased ?
In fact, the drying speed of a coating line, which not only concern the water contents but also need concern viscosity and vaporization of adhesives.

Definitely, more high viscosity glues will be more difficult to dry out the water. When coating the same solid content glue but different viscosity, then the lower viscosity glue will be dried fast, i.e. production will be fast.

Therefore, if who would supply you a higher solid contents glues, then you should also study its viscosity at first.
(Remarks: do select a low viscosity glue first, then take a higher solid content as possible.)

When we would deliver the tape roll for customer, we need calculate out:
How many rolls per carton ? What the size of per carton?
How many quantity can be load into a truck or a export container ?
Thus to know the outside diameter of the tape roll is required.

Definitely, we can measure the OD after we produced the tape roll, however,
if you could know the diameter in advance and estimate the loading quantity, then
the transportation cost will be under your control.

The calculate formula as follows:

If you’re headache with mathematics, then you may do calculation with EXCEL, as follows:

A & C are key-in by yourself.
B is a constants, no need change.
D is circle (Pi).
E is outside diameter of paper tube; if ID 3 inch core, you may keep 88 at this row.
F3 = SQRT(A3*B3*C3*1000/D3+(E3*E3))
G is key-in by yourself.
I is supposed quantity in per carton.
J is volume of per carton, usually 1-1.5 cube feet is most suitable for handling.
K is suitable quantity to load into a 20’ container, usually take 1000 cu.ft for per 20’ container, in calculation.

Definitely when winding tension is higher then OD will be smaller, but such tape may be telescope;
If winding too loose then the OD will be bigger then loading quantity will be less and pay higher freight.

Popularly, we use 5 kinds of adhesive for making the tapes, as: water base Acrylic adhesive, solvent base Acrylic adhesives, solvent base Rubber adhesives, silicon adhesives and Hot Melt Adhesives (HMA).

Due to it’s cheapest, acceptable quality, non-flame able and easy to apply, thus mostly we use water base Acrylic adhesive for making OPP tape.

Definitely, OPP tape can be coating with solvent base adhesives, popularly which used for cold area and frozen materials (vegetable & sea foods, etc.).

Definitely, OPP tape can be coating with hot melt adhesives, popularly which used for high ash area , like as textile industries.

Have we a multi purpose coating line ?

Or, can we use the same coating line to produce both OPP packing tape & PVC electric tape?

The answer is YES, but not good for operation.
Whoever spend a lot of money to invest a coating line, always expecting this line can be produce more different kinds of tape as possible. Unfortunately, due to different tape used different substrates and glues, has different requirement for end products, thus we suggest, it’s better to use a coating line for making- only 1 adhesive tape.

Usually we separate the substrates into 2 kinds – soft film and rigid film. The soft film like as PVC and PE; the rigid film like as OPP, PET, Paper and PI (Polyimide / Kapton), etc. Also, popularly the people use water or solvent Acrylic glue, solvent base Rubber glue, silicon glue and solvent base or solvent free silicon release agent, etc. for coating on these film. Also, the end product may in log roll, jumbo roll and sheet.

Thus, when some people insist to produce 3-4 kinds of tape by 1 coating line. Definitely, it may workable but not convenient for operation. A similar question – can we use a track to carry the people ? The answer is YES, but not comfortable.

When supply a coating line, we’ll consider (1) film (2) glues and (3) end products.

We may list some popular tape s as follows:

Tape	Unwind Film	Glue	Viscosity	End Products
OPP packing tape	OPP	water base Acrylic	low	jumbo roll
PVC electric tape	PVC	solvent Rubber	high	log roll (5-20 Mts.)
PE protection tape	PE	water or solvent base Acrylic	low	log roll (200 Mts.)
PET protection tape	PET	solvent base Acrylic	medium	jumbo roll
paper Masking tape	Crepe Paper	solvent Rubber	high	jumbo roll
Aluminum foil tape	release paper	solvent Rubber	high	jumbo roll
label sticker	release paper	water or solvent base Acrylic	medium	jumbo roll
tissue double side tape	release paper	water or solvent base Acrylic	medium	jumbo roll

Hence, when use a PVC electric tape coating line to produce PE protection tape, we need solve 2 problem, (1) different unwinding & rewinding system and (2) need different coator for different glue. Definitely, we may set-up whole different system on one coating line, however, it’s not comfortable for operation, and PE protection tape will get quality issue if used water base glue, due to solvent vapor will be condensed in chamber, which will drop and spot solvent on surface of water base tape then damage the quality.

The answer is minimum 43.2 tons annually. Yes, don’t be surprised.
How ?? Our calculation as follows:
If the coating speed is 100 meter/min,
if working width is 1000 mm and
If extra coating 1 gsm, then
100 meter/min *60 min *24 hours *1 meter * 1 gsm = 144000 g = 144 kgs per day

Further more,
144 kgs *25 days = 3600 kgs per month
3600 kgs *12 months =43200 kgs per year

The final answer is 43.2 tons annually free materials for your customer, if extra coated 1 gsm;
Of cause, if extra coated 2 gsm is 86.4 tons glue wastage.

When you supplied the tape with 1 gsm extra coated, the customer will be not appreciated, but if less coating for 1 gsm, you will get a lot of complain.

So, how the tolerance of coating thickness on your exist coating line ?
