Delta ST Star-sealed T-shirt bags
For production of star-sealed T-shirt bags on roll in 1 or 2 lanes. The configuration is identical to the Delta T, for production of conventional T-shirt bags, with addition of the “star-sealed kit”, a patented concept that allows production of star-sealed and conventional T-shirt bags in the same line. The configuration includes a Delta sealing module, a punching module for cutting out the handles of the T-shirt bag and an extraction module for removal of the cut-out waste. The flexible dies in the punching module are fixed to a magnetic roller and can be changed to another cutting pattern within a few seconds.
A patented concept makes it possible for the shaped cut-out to be done before perforation and sealing. This ensures that cutting is done in a zone with precise tension control, giving a clean cut and accurate positioning of the cut-out, minimizing skirt variation. All bag types can be produced perforated or interleaved. It is possible to integrate automatic roll handling/packaging to your Delta line.
