STUFFING TABLE SECTIONS: 1st section: Mechanism for insertion of 30 - 40 single end ribbon yarn stuffers feeding from the sup- plied spool creel; stuffer yarn cutting device 2nd section: Tables with conveyor belt, device for conveying and stretching the spiral mesh 3rd section: Slide with clamping device for stuffers and stuffer yarn inspection METHOD: The ribbon yarn stuffers (1-30 or 1-40 piece) are inserted all at once into the stretched spiral fabric. After previously setting the ribbon length, the machine cuts the stuffers auto- matically. Once the stuffer insertion tool is in the initial po- sition, the operator starts the table take-up drive again to move the spiral fabric forward to the next preset position for stuffer insertion. The target position for stuffer insertion is controlled by a laser. The machine has the possibility to stuff non-heatset fabrics in either straight or angled position for insertion of stuffers as well as previously heat-set fabrics with straight insertion of single end ribbons. All electronic and mechanical featu- res are included to operate both insertion methods. On the stuffer insertion side there is a cutter installed to cut the fabrics to a straight cut to help with positioning spiral coil openings for inserting the flat ribbon yarns. FABRIC STYLES: For previous heat-set fabric an important factor for a good semi-automated run is the resultant spiral quality from the heat-setting procedure. The spiral size should always be within the indicated tolerance as well as have a clean and straight cut in order to ensure an uninterrupted auto- mated program sequence. The spiral coil opening pitch frequency for insertion of stuffers and the straightness of the fabric should be perfectly aligned into position. For non-heatset fabrics it is important that the segments at the assembly machine are also aligned perfectly. * Hot Air free shrinkage at 200°C We reserve the right to make technical improvements without notice.
