Abstract

556,234. Cutting-apparatus for paper, leather &c. SADGER, A. Oct. 13, 1942, No. 14347. [Class 31 (i)] Articles of leather, paper, cardboard, jointpacking material &c. are cut-out by dies in the form of band steel cutters a, b of appropriate shape which are secured to a mouldable material D in moulds A, B, Fig. 3, prior to being mounted in a metal frame F, Fig 1, to which a cover G is secured by means of bolts and nuts, h, i. Spring- ejectors d are arranged near the cutters, and during the moulding operation dummy cores e, f are arranged in the mould to provide spaces in the material D to receive the bolts and nuts h, i and the ejectors. A layer of plaster of paris g is first poured into the mould to secure the parts temporarily in position, and then the material D is inserted. This may consist of metals or alloys, cement mixed with fibres, chlorinated or sulphurated bitumen or hydrogenated oils, thermoplastic and/or thermosetting substances, or glue or mixtures containing glue. When the material D has set the bedding substance g is removed and also the cores e, f. The ejectors are inserted, and the bolts and nuts operated to screw on the cover G. The cutting- blades are preferably slotted at their upper ends so as to permit of the material D being moulded as one homogeneous piece. In a modification Fig. 5, for forming packing rings, concentric cutting-knives n, o of different size are used. and with sets of five knives of each kind rings of twenty-five sizes can be obtained. The die-members n, o are connected by a plate J which has radial recesses R for accommodating the ejectors. For centering the die-members n, o the cutters and stock are formed with rectangularly placed slots into which engage splines N, Fig. 6 (not shown), on the bedplate J.
