Test preparation
Adjustment knob until the tab located at the highest position of the clamping device B, and this means added fixed pad
The zipper pull tab secured to the pull-tab clamp B.
First zipper trailing end (lower end stop) roughly fixed to the upper clip within the first A point (in this case the first clip and zipper center vertical centerline).
The zipper front end (top dead end) fixed to the two longitudinal clip head at point E（E-point clip longitudinal head when holding the specimen cannot be clamped sprocket, two specimens shall live clip head in the same positionTwo longitudinal vertical line clip head and the edge of the vertical zipper teeth）.
A long sword head slightly loosen the fixed point, the end of the zipper pulled up so that the rotating plate and sheet G horizontal line H parallel, then the head at point A clamping clip (this time longitudinally visually clip the first two points in the same horizontal line E )
Adjustment knob until the tab clamping device B at the lowest position is reached, the two lateral head D Release the clip, so that both sides of the fastener tape into two clamping fixture (in this case two lateral visual clip head and perpendicular to the fastener the same level), chuck from the side edge of the fastener should be 5.0 mm gap.
Lateral adjustment by zipper type spring balance, Nut fastener tape is applied to the upper and lower of appropriate lateral load as shown in Table 2:Adjustment on both sides of the adjusting screw C and D there are two sides of the collet 5.0 mm distance.
Steps of Zipper Reciprocating Pull Tester:
1. Place the tension machine on the horizontal table and fix the base.
2, installation pointer push tension meter (screw off, with a cross to bag accessories 4 screw off, will the attached bag four phillips screws through the mounting holes on dynamometer installation plate, screwing in dynamometer 4 M3 threaded hole on the back cover, remove the screw thread hole), installed after pushing tension meter table, use the M4 Allen wrench to install the dynamometer plate installed on the frame. According to the sample characteristics of the required test, install or install it on the platform. Rotate the hand wheel on the side of the test frame, and the dynamometer can move smoothly up and down, completing the test work.
3. Install the fixtures required for testing and adjust the position.
4. Adjust the height and position of the bottom fixture continuously, so as to make it fit in the upper stretching fixture.
5. Place the sample on the bottom clamp and fix the button position with the bottom clamp.
6. Adjust the tension meter to make the pointer of the pointer pull down vertically (to zero).
7. Rotate the handwheel slowly until the button on the sample is out of sample.
8. Record the reading of the pointer at this time, return the pointer to zero after completion, repeat the above steps to test several times, and record the measured values.
