Abstract
A system for processing a line of material along a path and a tear-assist apparatus. The tear-assist comprising a driving portion that drives the line of material along the path, a sensing unit that detects pulling of the line of material in a first direction along the path away from the driving portion, and a cutting member for cutting the line of material. The driving portion can also be configured to drive the line of material in the first direction along the path to dispense the material.
Claims18
A dunnage converting apparatus, comprising:
- a converting station operable in a converting direction for converting supply material into low-density dunnage and moving the dunnage in a dispensing direction along a material path;
- a cutting member disposed on a single lateral side of the material path, the cutting member dividing the path and dunnage therein into:
- an outfeed portion between the converting station and the cutting member, and
- a severable portion beyond the cutting member from the converting station;
- and
- a reverse-driving element that is operable to pull the dunnage against the cutting member to cause the cutting member to initiate a cut of the dunnage at the cutting member.
