Elastic cloth is popular in the market. Customers who buy jeans need to see if there is elasticity. Elastic cloth is favored by the majority of users because of its flexibility. However, elastic cloth will slip when sewing. If you don't master the method well, there will be jumping in the sewing process. Therefore, by adding a pneumatic telescopic brace, the elastic material is stretched to a state that is not easy to slip, and the material is assisted by the rear tugboat device. Because the whole machine is cylindrical, it is convenient for the operator to directly insert the elastic material and sew it together, which improves the overall efficiency.
For sewing elastic waistband inside pants or jeans, we`ll be glad to help you with this machine. Please don`t hesitate to contact us anytime.

Glow- Wire Tester:
Product details: Model ZLT-GTR:
To determine the fire resistance by the fire hazard test, accordance with IEC60695-2-10, IEC60335, IEC60598 and other standards.
The ignition source is imitated by an electrically heated wire loop against which the sample is pressed with a constant force. A miniature jacket thermocouple serves as a sensor for the loop temperature.
The sample has to be fastened to a carriage on which, by means of a tensioning cord, a weight with a force of 1 N is effective in the direction of the wire loop. Scales enable the reading of the flame height and the depth of penetration. Approx 200 mm below the wire loop a board of pine wood, covered with a layer of tissue paper, is mounted. This device enables to judge the danger of a fire spreading through burning drops or glowing parts falling from the sample. The calibration is done with silver foil, when the foil melts, the measuring unit must indicate a temperature of 960 ° C.
Standard outfit:
1 wire loop of nickel-chromium, Φ 4 mm, accordance with IEC60695-2-10 figure 1, with clamping mechanism, with Φ 0, 6 mm for the thermocouple,
1 carriage with fixture for the specimen, with a rate of approach and withdrawal of 10 mm/s to 25mm/s,
1 fine rope pull mechanism with weights for loads of 1± 0, 2N,
1 gauge of 7 mm for the depth of penetration, with maximum pointer and stop,
1 scale to measure the flame height,
1 high current isolating transformer to heat the wire loop, with series connected variable ratio transformer, to set the temperature up to 960± 15 ° C,
1 type K thermocouple Chromel-alumel, Φ 1,0 mm, length approx. 500 mm, to indicate the temperature of the glow-wire loop, with digital display measuring range 0~1050 ° C, built-in operable,
1 chamber with a volume of at least 0, 5 mm3, black interior,
1 wooden board, 10 mm thick, 10 sheets of wrapping tissue, of grammage between 12g/~30g/.
Power supply: 220V50Hz other voltages request.
