PTW-1200 Series | Open-Mouth Baggers

Open-mouth bagging machine | Bagging machine for polywoven bags

    The PTW-1200 Series Automatic Open-Mouth Bagger (patent pending) is a highly efficient system that has been designed to easily run porous polywoven bags, which are often used in manual bagging operations.

    The PTW-1200 offers a new, innovative solution for improved bag separation. Its new technology combines two complementary systems to separate bags at both ends. This is a dependable and efficient solution for porous polywoven bags that could stick together because of static electricity, twisted thread and other reasons. The PTW-1200’s innovative way to feed bags into an automatic bagger has been merged with the proven robotic full-bag exit system, producing a fully automatic bagging solution that replaces a manual equipment line.

    This bagger is equipped with devices that detect bag thickness, bag-on-spout placement and an open bag at every step of the process. These detectors spot a closed or misplaced bag on the spout as well as multiple bag picking allowing the machine to reject these bags automatically without stopping the bagging process. 

    All these features are designed to optimize production despite the irregular properties of porous polywoven bags.
