Abstract: An apparatus for forming packaging material into a tubular form includes angularly disposed forming rollers for causing the longitudinal edges of the packaging material to overlap one another so that they can be sealed together. To prevent the packaging material tube from being trapped between adjacent rollers, each of the forming rollers can be provided with one straight roller edge and one chamfered roller edge. The rollers are positioned such that the chamfered roller edge of one forming roller cooperates with the straight roller edge of the adjacent roller, thereby defining a nip directed generally tangentially to an adjacent portion of the packaging material tube. Alternatively, to achieve the same objective, two different types of forming rollers can be employed, one type in which both roller edges are straight and another type in which both roller edges are chamfered. In this latter case, the two types of rollers are alternated with one another.

These angular positions correspond to respective work positions in which the tool can be held by the operator.

Abstract: A tooth for use in a comminuter roll comprises a roll of spring steel having a first end formed into a point or other abrading shape. The tooth is compressed upon insertion into a mounting hole in the roll and the inherent spring of the steel tends to force the tooth back to its original size, thereby creating forces on the interior of the mounting hole to form an interference fit that holds the tooth in place in the mounting hole. In a preferred embodiment, the tooth is formed of a roll of spring steel having a G-shaped cross section. This shape provides an opening through the length of the tooth and also leaves a solid piece in the center of the tooth to aid in tooth removal. A rod can be slipped through the lengthwise opening of the first tooth so that its end abuts the solid center portion of the second tooth that is colinearly mounted in the other end of the hole that the first tooth is mounted in. Tapping the rod will force the second tooth out of its hole without disturbing the first tooth.
