1341662 Shearing; hold downs; consolidating scrap MASCHINENFABRIK HASENCLEVER GmbH 12 April 1972 [29 April 1971] 16943/72 Headings B3W and B3H A ribbon of scrap metal compressed by a hold down 7 is cnt into lengths by a blade 6, co-operating with a blade on a cutting table 3, the blade holder and the hold down carrying stroke-limiting limit switches 10, 12 mounted on switch bars 8, 9 respectively. The actuator 11 for the blade switch 10 is mounted on the hold down switch bar 9, the vertical distance from the lower face of the blade holder to the switch 10 being smaller preferably by 2-10 cms. than the distance from the lower face of the hold down to the actuator 11. In operation, at the end of a cutting stroke by the blade 6, the hold down 7 has compressed the next length of the ribbon 1 as shown in Fig. 1. Downward movement of the blade 6 is reversed in conventional manner; its upward movement ends when limit switch 10 is actuated by actuator 11 on the hold down switch bar 9. Simultaneously the hold down starts its up stroke and when it reaches its uppermost position actuator 13 on the shear frame actuates switch 12 on the hold down to cause a feeder 4 to advance the length of compressed ribbon 1 below the blade 6. The next down stroke of the hold down 7 compresses the following length of the ribbon until a predetermined pressure is reached when a pressure sensitive switch starts the blade holder on its down stroke. The switch 10 or the actuator 11 can be adjustably mounted.
