Abstract

947,250. Cutting apparatus. J. SANDT A.G. Sept. 8, 1960 [Sept. 8, 1959], No. 32340/63. Divided out of 945,944. Heading B4B. A machine for punching sheet material comprises a punching press 1 having a punching beam 17 reciprocable in an up and down direction, a feedway 2<SP>1</SP> extending transversely to the direction of movement of the beam from at least one side of the press and of sufficient length to accommodate at least two punching tables 21, 22 movable into and out of the press from the same side of the press, and at least one lifting device 25, 26 for lifting a first table 21 into a loading and unloading position so high above the feedway that another punching table 22 can be moved below the first punching table from an initial position, situated on the feedway further from the press than the first table, into the press for punching and returned to the initial position, the lifting device then being operable to lower the first table on to the feedway for movement into and out of the press. As described in Specification 945,944 the punching tables may be longer than the beam and are moved stepwise through the press so that the beam acts successively on the material 23 and tools 24 on the tables, an extension 3<SP>1</SP> of the feedway accommodating the tables as they are fed through the machine. A similar arrangement of feedway, punching tables and lifting device may be disposed on the other side of the press, the tables being fed alternately from opposite sides of the press under the punching beam. More than two punching tables may be provided on one or both sides of the press, lifting devices being provided for each table other than the one or ones whose initial positions are furthest from the press.
