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.

Label roll manufacture

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.

Star trip label stripper

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.

Label matrix stripping

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.

Deflectable bearer roll

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.
