Abstract
1446510 Benching; making fork lift blades BYGG-OCH TRANSPORTEKONOMI AB 19 June 1974 [21 June 1973] 27247/74 Headings B3E and B3A [Also in Division B8] A member of profiled section, e.g. a fork lift blade, is made from sheet or plate metal by the steps of bending a first part of an edge to form an obtuse angle with the plane of the sheet, further bending the part to form an acute angle and bending a further part of the edge to form a right angle, folding over the first part to lie adjacent the sheet, and bending up at least part of the edge formation so obtained at right angles to the sheet. In the embodiment described, the whole of the edge formation is so bent up, and the whole process is carried out on both sides of the sheets to obtain the blade shown in Fig. 5, of which the folds shown in section B-B have been formed in three steps, the outmost right angles of section C-C being formed in the second of those steps. In the fourth step, in which the folds in section B-B are bent up and the channel sections at each edge in section C-C are formed, a flange is also formed at the blade front as in section A-A.
