Abstract: Two-out terminal strip (44, 44') is produced by stamping and forming the strip such that the terminals (40) on one of the side edges (36) extend laterally in a first direction of the plane of the stock strip (124) and the terminals (40') on the other side edge (36') extend laterally in a second direction which is the opposite of the first direction. The two-out strip is slit along the centerline (30) of the central carrier portion and the resulting single strips (44, 44') of terminals are wound on reels (46, 46'). One of the strips (44') is wound by rotating the reel (46') in a clockwise direction and the other strip (44) is wound on a reel (46) by rotating the reel in a counterclockwise direction. The two strips will then be in the same orientation on their respective reels and re-reeling of one of the strips is not necessary.

Abstract: The outer portion of a die stamped metal frame encompassing the outer ends of the electrical connecting pins is subjected to press striking for re-establishing planarity and parallelism of the opposite faces of the patterned pins which have become deformed during the die stamping, before proceeding to the assembly operations.

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.
