Abstract (en)
The invention relates to a corner knife mechanism (100A, 100B) of a welting machine (10). The corner knife mechanism (100A, 100B) includes a plurality of first corner knives (101, 102, 101A, 102A) having different cutting edge angles (¸e1, ¸e2) or different mounting angles (¸1, ¸2), a plurality of second corner knives (103, 104, 103A, 104A) having different cutting edge angles (¸e3, ¸e4) or different mounting angles (¸3, ¸4), a corner knife holder (105) on which the first and second corner knives are arranged, a knife selecting actuator (121) which moves the corner knife holder (105) in a direction (Y) along which of the first and second corner knives are arranged, a cutting actuator (131, 132) which selectively moves up and down the first and second corner knives; and an operation control means (80) which controls the knife selecting actuator (121) and the cutting actuator (131, 132) to select a combination of one of the first corner knives and one of the second corner knives and to form a corner cut. The first corner knife and the second corner knife of the combination are symmetrically oriented with respect to the cloth feeding direction (F) and have the same mounting angle (¸1, ¸3; ¸2, ¸4) or the same cutting edge angle (¸e1, ¸e3; ¸e2, ¸e4).
