Rolling assembly for packaging web material in a roll
A rolling assembly for packaging web material in a roll has been granted a patent (Publication Number: US11897713B2). The assembly comprises a base member with a concave arcuate feed surface, a first intermediate member with an arcuate pressure surface, and a top member with a concave pressure surface. Together, they form an iris with a feed space that adjusts between a first and second condition as the roll of web material increases in size. The assembly is designed to receive web material and direct it upwardly to form a roll within the feed space, with pressure applied by the intermediate pressure surfaces as the roll expands.
The system for packaging web material in a roll includes a feed assembly for carrying the web material and a rolling assembly to receive it. The rolling assembly, similar to the previously mentioned patent claims, consists of a base member, first intermediate member, and top member forming an iris with a feed space. The method for packaging web material in a roll involves delivering a stream of web material to the assembly, where the iris receives and directs the material to form a roll. The first intermediate member applies pressure on the roll as it expands, ensuring proper packaging of the web material, particularly plastic bags in a shingled arrangement. This patented system offers a unique and efficient way to package web material into rolls with precision and control.
