Document Type and Number:
Japanese Patent JPS5321156
Kind Code:
B2
Abstract:
Successive spaced cuts, notches, imprints or other marks are made along the edges of a moving web by members that are driven with harmonic motion by conversion of rotary motion to reciprocating motion. As the web moves onto and partially around a drive roll that carries the marking members, the latter are reciprocated in paths extending obliquely toward the roll axis from outboard of the web edges. At least one ring eccentrically encircling the roll outboard of the web is driven from the roll at constant angular velocity by cam and follower means. Each ring is connected by a ball-in-socket-like connection with the outer ends of the associated members to reciprocate the members with a stroke corresponding to the degree of eccentricity of the ring relative to the roll.
