Abstract: In an automatic screw machine two spindles are mounted coaxially one within the other and are keyed together for rotation in unison in the indexing head of the machine. The inner spindle has a collet on one end thereof; the outer spindle is shiftable axially relative to the inner spindle between collet opening and closing positions. A spring, which surrounds the inner spindle at one end thereof, urges a washer on the inner spindle against one end of the outer spindle normally to urge the outer spindle resiliently into a collet closing position. A hydraulic cylinder, which surrounds the outer spindle at the side of washer remote from the spring, contains a piston which is engaged at one side with the washer and at its opposite side communicates with a fluid pressure chamber. To open the collet pressure is applied to the fluid in the chamber, thereby causing the piston to compress the spring and to permit the outer spindle to move to a collet opening position.

Abstract: A pair of spindles are journaled coaxially one within the other in the indexing head of an automatic screw machine, and with the outer spindle disposed to be reciprocated axially between first and second limit positions in which it opens and closes, respectively, a collet which is supported by the inner spindle in the bore of the outer spindle. The outer spindle is urged axially to a collet closing position by a compression spring; and a camming element is rotatably adjustable about the outer spindle between a first position in which it urges the outer spindle axially rearwardly against the resistance of the spring to open the collet, and a second position in which it permits the spring to return the outer spindle to a collet closing position. The spring tension is adjustable by another element which is threaded on the outer spindle.

Abstract: Paper label stock combined with liner material is butt cut to provide labels surrounded by a "rungless" ladder-shaped matrix whose side rails have relatively straight borders and can be relatively easily stripped. The labels, as formed, are adjacent each other, but are repositioned and spaced by off-feeding the labels from their original combination with liner material, and redepositing them on liner material moving in a path at 90 degrees to the direction of off-feed. When the labels are subsequently applied to a cylindrical container or the like, the grain of the labels is parallel to the axis of the container. In a label roll so manufactured, the grain of the labels runs crosswise.

Abstract: A game is played on the playing surface of a board divided into at least three rows of squares with identical pieces except for player distinguishing markings, each piece being cubic in shape and having each of the three pairs of opposite sides thereof marked with distinguishing insignia. Each insignia designates a mode or characteristic to be assumed by the piece when the side of the cube faces upwardly. The rules provide details for playing a game utilizing such board and pieces in which the three modes are characterized as aggressive, impregnable and vulnerable.

Abstract: Peel-back separation of labels from a supporting liner is enhanced by delivering a sharp blow in the vicinity of the leading edge of each successive label. In a preferred form of the invention, the sharp blow is delivered by means of a star wheel head.

Abstract: A series of labels remain supported on a liner after a matrix of waste label material has been stripped from the liner. The adhesion of the matrix to the liner is weakened prior to stripping of the matrix by mechanically disturbing without severing, as by embossing, areas of the construction where the matrix overlies the liner. Areas where the leading ends of labels overlie the liner may also be similarly disturbed to make eventual peeling of the liner from the labels easier. In another aspect, the construction may be precrushed with a blunt die prior to die-cutting of the labels to eliminate "halo" effect upon stripping of the matrix.

Abstract: This invention relates to die-cutting roll presses and, more particularly, to a means for adjusting the spacing between the axes of the anvil roll and the die roll of a press.

Abstract: A die-cutter assembly including a die-cutting roll and an anvil roll between which a web of material is passed for die-cutting of labels. Spacing between the rolls is controlled by a pair of bearings at each end of one of the rolls, each pair including an inner bearing in which the roll is journaled and an outer bearing which is in rolling contact with the die-cutting roll. A rotatable eccentric spacer between the inner and outer bearings provides an adjustment of the spacing between the axis of the cutting roll and the axis of the anvil roll.
