PROCESS FOR MANUFACTURING BAGS WITH ADDITIONAL CLOSING PROFILES, MACHINE AND BAGS OBTAINED

摘要

The procedure for making plastic film bags with interlocking fastening strips operated by sliders consists of feeding the film material (110) and fasteners (10) separately into the bag-making machine, incorporating a phase in the sequence to detect any fault in sequence between the delivery of the fasteners and the operation of transverse seam welding jaws (140), and making the necessary adjustment to the position of zones of reduced thickness (60) between fasteners.
