Abstract
A lateral sheet registering device for registering sheets transported along a predetermined path including a lateral registration edge positioned along the path. An active lateral registration apparatus urges sheetlike material into contact with a registration edge guide member as the material is advanced in a process direction of travel. A wear resistant contact surface is provided along an inboard side of the registration edge guide by mounting a plurality of dowel pins fabricated from a particularly wear resistant material along the registration edge guide. The dowel pins are mounted so as to be rotatable and/or replaceable without the requirement of replacing the registration edge guide or removing the sheet handling system.
Claims10
An apparatus for registering a sheet material moving along a process direction of travel, comprising:
- a registration edge guide member defining a surface substantially parallel to the process direction of travel;
- means for driving the sheet material laterally relative to the process direction of travel, to urge the sheet material against said registration edge guide member to provide proper alignment and registration of the sheet material;
- and
- a wear resistant contact surface positioned along an inboard surface of said registration edge guide member, for providing a wear resistant surface against which the sheet material is urged to eliminate excessive wear of said registration edge guide member, wherein
- said wear resistant contact surface includes at least one dowel pin member mounted on said registration edge guide member for providing the wear resistant surface against which the sheet material is urged;
- said registration edge guide includes at least one receiving aperture for mounting said dowel pin member therein;
- and
- each said dowel pin member is selectively rotatable within a respective receiving aperture for providing extended life to said dowel pin member by permitting rotation thereof without replacement of said registration edge guide member.
