WORKING PROCESS FOR PRODUCING POCKETS AT THE ENDS OF SLATS OF A WEB OF SLATS MADE OF FLEXIBLE MATERIAL AND DEVICE FOR CARRYING OUT THIS WORKING PROCESS

摘要

A working process for producing pockets at the ends of slats of a slat web made of a flexible material and to a device for carrying out this process. The essential feature is the arrangement of a feeding device, by means of which the section of a weblike welding flux needed for a welding process can be inserted transversely to the longitudinal direction of the slat from the side into the partially open slat pocket, and the welding flux is fed at a linear distance.
