Product Group:	Polyamide power transmission belts
Joining System:	Thermofix

• Joining is also possible with other Habasit devices.
• Machine setting data should be derived from the relevant operating instructions.
• Read the operating instructions of the necessary tools carefully before making the first joint.
• All data are approximate values and defined under the following standard climatic conditions:
  > 23 °C/73 °F, 50 % relative humidity (DIN 50005/ISO 554), working voltage 225 - 235 V / 105 - 115 V.
  > Any change of these data may require different temperature and/or time and/or pressure.
• For further support, please contact the Habasit company responsible for your location.

Skiving device:	AT-300/301

Recommended joining angle:	90°
Skiving angle (setting value):	3
Paper grit:	50
Target Skiving Length:	45-60 mm 1.8-2.4 inch
Working Length:	85 mm
Feeding speed, advance:	30
Feeding speed, return:	50

Skiving explanation:	Joining angle of 90° for low speed (v < 20 m/s) power transmission belts - folder gluer belts - tube winders. Joining angle of 75° for high speed (v > 20 m/s) power transmission belts and tangential drives.

Step 1 > Mark off elastomer (friction cover) and polyamide areas (traction layer and intermediate fabric layers) with fine straight lines running parallel to the cutting edge (ball point pen or pencil). > Mark limit between Fixol and Vulcol always just within the area of pure polyamide fabric. Fixol does not stick elastomer. > Use spatula or brush. Coat evenly and THINLY indicated elastomer areas (friction cover) of BOTH skived surfaces with Vulcol (see sketch). Avoid applying Vulcol twice. > Allow to dry for about 10 min. > Use an acid-resistant brush. Coat evenly and THINLY the indicated polyamide area (traction layer and one of both intermediate fabric layers) of BOTH skived surfaces with Fixol (see sketch). > Rub in with brush (on traction layer only) until Fixol becomes tacky. > Allow to dry for about 2 min. > The adhesives must exactly cover the prescribed surfaces. Put skived surfaces accurately on top of each other at the first attempt. Vulcol sticks on contact! > Close adhesive containers well.

Pressing Remarks:	REMARK: Carry out a QUALITY CHECK! - Meassure thickness over the joint area. In the center it must be: -0.05/+0.05 mm / -2/+2 thou. And over the whole area: -0.05/+0.10 mm /-2/+4 thou. According to experience‚ application requirements or customer recommendation the thickness of the joint area can deviate from above specification.
