Abstract
A loom speed controlling apparatus includes a counter adapted to output a current pick number, a data memory for storing the maximum allowable loom speed values depending upon physical characteristics of various filling yarns in correlation with pick numbers, and a discriminator for determining a target rotational speed of a driving motor for the loom in accordance with the current pick number supplied from the counter and data supplied from the data memory. An indexing signal generator is connected to an input of the counter and an inverter for variable-speed operation of the loom driving motor is connected to an output of the discriminator and the index signal generator includes a plurality of proximity switches adapted to be disposed close to a loom spindle and the indexing signal generator.
