Applicant: Carr Cedar Products, Inc. Title: Shim Bundle and Method of Making the Same ABSTRACT Several courses of random width, low-grade tapered wood shingles are stacked in an elongated trough with the butts of shingles of adjacent courses disposed at opposite sides of the trough to form a substantially continuous stacked shingle lay-up. A cutoff saw consecutively cuts loose packs of shingles from an end portion of the lay-up. After each pack- cutting operation, the lay-up is shifted lengthwise of the trough to a position for the saw to cut another pack from the lay-up. Each severed pack is banded about its center to form a bundle, moved lengthwise partway through a gang saw to form a set of parallel kerfs spaced apart uniformly widthwise of the bundle and extending from an end of the bundle almost up to the band and then turned end-for-end and moved length- wise partway through the gang saw to form another set of kerfs extending from the other end of the bundle almost up to the band. The kerfs of the two sets of kerfs are in registration. In use, the bundle band is severed and the kerfed shingles may be separated into narrow individual builder's shims by breaking the short shingle portions between oppositely extending registered kerfs.
