A Coreless Shaft is a shaft that winds paper, film or foil with no core. If the material being wound is going direct to the consumer for example, there may be no need to include a core with the roll. By eliminating the core, the manufacturer not only saves thousands in core costs, but also eliminates the need for his customer to send the unused cores to the landfill.
Multiple shaft designs now available for winding paper, film or foil with no core saving converters thousands in core costs and eliminating the need for core disposal.
The new Goldenrod 1260-LFT multiple bladder winding shaft features a fixed trapper
leaf with a full-length trapper ledge. The leading edge of the material is inserted directly into a slot under a fixed leaf in the shaft, where it is secured when air is introduced.
Older style trapper leaf designs held the leading edge with a spring lever. A hybrid to
this design works especially well for automatic machines that orientate the shaft, feed the material into the slot, wind and release automatically.
Coreless winding is ‘green’ as it eliminates the need to dispose of cores. And of course, it saves money. Virtually any converting application can benefit from coreless winding.
Applications such as shrink film, landscape film, rubber roofing, plastic fencing or netting, or any other material that after it is used, requires the core to be disposed of, is a candidate for this new technology.
