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 sensing unit can be associated with the driving portion such that upon detecting movement of the line in the first direction, the sensing unit causes the driving portion to drive the line of material in a second direction along the path for drawing the line of material against the cutting member to cut the line of material. In another configuration, when the sensing unit detects the movement in the first direction, the sensing unit can cause the driving portion to, drive the line of material in the second direction sufficiently for severing the portion of 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.
