Abstract
A plow for use in a machine in the printing industry to provide for the folding of a paper web thereover. The plow through its novel mounting structure in the machine may be adjustably positioned relative to a frame support throughout a wide range of movements in all directions to accommodate any desired paper web travel through the machine. Adjustment of the plow position may be made while the paper web is moving through the machine to insure the proper and accurate guiding of the paper web through the machine.
Claims9
A paper plow support for printing industry machines comprising spaced apart stationary side frame members, a transverse beam journally mounted for rockable movement in said stationary side frame members, means interposed between said beam and at least one of said side frame members for adjustably rocking said beam, a support member carried on said beam, means adjustably positioning said support member axially along said beam between said side frame members, means locking said support member in its adjusted position, a post, means moving said post relative to said support member at generally right angles to the axis of said beam, a cylindrical member mounted on and carried on one end of said post with the post disposed radially inwardly of said cylindrical member a limited distance, means locking said cylindrical member in any desired arcuately swung position about a longitudinal axis of said radially disposed post, a shaft mounted in and through the axial center of said cylindrical member and disposed at right angles to said radially disposed post, a cylindrical paper roller mounted on said shaft and abutting one end of the cylindrical member, and a plow having a flat portion and an arcuately upturned circular end, said arcuately upturned circular end having substantially the same diameter as the cylindrical paper roller and having its center coaxial with the axis of said shaft carrying said cylindrical paper roller, and means locking said plow in any desired rocked position about the axis of said shaft.
A plow for paper webs comprising a relatively thin piece of material having a generally rectangularly shaped flat portion defining oppositely disposed narrow ends and an arcuate circular portion upturned from one of said narrow ends of said rectangularly shaped flat portion and the flat and circular portions jointly forming a smooth undersurface, said arcuate circular portion having an extent at least one-quarter of the arc of an entire circle about an axial center of said arcuate circular portion, a bracket affixed to said flat portion and extending upwardly in the same direction as the upturned arcuate portion, said bracket having a pivot center located on the axial center of the arcuate circular portion of the plow, a shaft having its axis on the axial center of the arcuate circular portion of said plow, said bracket adapted for journal mounting on its pivot center about said shaft, and means adjustably positioning said plow about said pivot center.
