    • Apparatus for determining the length of portions cut from stock material characterised by a stock pulse generator 15 responsive to the movement of the stock past a cutting device 10 to provide a stock pulse train, the repetition rate of which is related to the speed of advance of the stock; a cutter pulse generator 17 responsive to the cutting device for producing a cutter pulse train, the repetition rate of which is related to the frequency of cutting operations of the cutting device, a counter 40 for counting the pulses produced by the stock pulse generator; means 38 for starting the counter in response to a cutter pulse and for stopping the counter after a predetermined further number of cutter pulses have been generated, whereby the number of stock pulses then recorded by the counter is representative of the length of the last n portions cut from the stock, n a predetermined integer in excess of one.
    • 用于确定从库存材料切割的部分的长度的装置,其特征在于库存脉冲发生器15,其响应于库存通过切割装置10的运动以提供库存脉冲序列,其重复率与前进速度有关 股票 刀具脉冲发生器17,其响应于切割装置产生切割脉冲串,其重复率与切割装置的切割操作的频率有关;计数器40,用于对由脉冲发生器产生的脉冲进行计数; 用于响应于切割脉冲启动计数器的装置38,并且在已经产生预定的另外数量的切割脉冲之后停止计数器,由此由计数器记录的存储脉冲数代表最后n个部分的长度 从股票中切出,超过一个预定的整数。
