Abstract
The invention relates to a method of trimming selvage from a succession of books. According to the method, a saw is provided having a pair of oppositely facing surfaces which merge at a cutting edge. One of the surfaces is substantially flat throughout its length or throughout all but the area of the surface adjacent the cutting edge. The latter area is bevelled as is the other surface of the saw. The books are advanced toward the saw and the saw is so positioned relative to the books such that its cutting run is normal to the direction of book advance and is parallel to the plane of the pages of the books. The saw is also positioned such that its first-mentioned surface faces pages trimmed by the saw and its other surface faces selvage trimmed by the saw.
Claims9
A method of trimming selvage from a plurality of books including the following steps:
- providing a saw having a pair of oppositely facing surfaces which merge at a cutting edge, one said surface having first and second portions, said first portion extending from a base of said saw to said second portion and being disposed substantially in a plane parallel to the cutting run of said saw and said second portion extending from said first portion to said cutting edge, the other said surface being oriented at an oblique angle to said cutting run plane;
- causing said books to advance downstream to said saw;
- positioning said saw relative to said books such that the cutting run of said saw is both normal to the direction of advance of said books and is substantially parallel to the plane of the pages of said books and such that said one surface faces pages to be trimmed by said saw and the other said surface faces selvage to be trimmed by said saw;
- and trimming said books by means of said saw.
A method of trimming selvage from a plurality of books including the following steps:
- providing a saw having a toothed cutting edge, each tooth defined by a pair of oppositely facing surfaces which merge at a cutting edge, one said surface having first and second portions, said first portion extending from a base of saw to said second portion and being disposed substantially in a plane parallel to the cutting run of said saw and said second portion extending from said first portion to said cutting edge, the other said surface being oriented at an oblique angle to said cutting run plane;
- causing said books to advance downstream to said saw;
- positioning said saw relative to said books such that the cutting run of said saw is both normal to the direction of advance of said books and is substantially parallel to the plane of the pages of said books and such that said one surface faces pages to be trimmed by said saw and the other said surface faces selvage to be trimmed by said saw;
- and trimming said books by means of said saw.
