Abstract

1397529 Stretching SCHLOEMANN-SIEMAG AG 31 Jan 1974 [31 Jan 1973] 04443/74 Heading B3E A stretching machine comprises two gripping heads 6, 8, power means 10 for drawing one head away from the other to stretch a length of stock, a transmitting member 1 coupled to move with one head 6, a rotary sensing member 12 which rolls on the transmitting member 1 and is coupled to move with the other head 8, and means 13 associated with member 12 to derive a signal representing percentage stretch of the stock. As shown, member 1 is an endless rope or chain connected by rigid link 4 to head 6, and member 12 is a pulley connected to head 8 by a rigid link 4a and driving a position transducer, e.g. a rotary potentiometer 11. When head 6 is adjusted on guides 5 to accommodate a workpiece 9, potentiometer 11 transmits a signal representing the length of the workpiece to a computer 13. As the workpiece stretches, the change in length is sensed by the potentiometer and computer 13 derives a percentage length change signal, which may be used to stop the stretching when a predetermined strain is reached. The potentiometer may generate a digital signal. The rope or chain 1 may pass around pulley 12. In another embodiment the member 1 is a rack sliding in fixed guides, and the rotary sensing member is a toothed wheel.
