is set to auto-return when it subtracts 1 count for 1 pulse and reaches "0", and 0 detection 6
At the same time, it is relayed to the stepping motor control circuit 7, and further relayed to the stepping motor drive circuit 8.
The stepping motor 9 is rotated by a predetermined angle per pulse, and the material 11, such as rubber, is fed by a feed roller 10 provided on the same axis, and stitching is performed in synchronization with the fabric feed of the sewing machine at high speed. This is the configuration of a rubber fabric feeding device having a circuit.

なるとオートリターンするようにする。 The present invention is constructed as described above. For example, 1.
The sewing machine 1 rotates at 7000 revolutions per minute, and the rotary encoder 2 rotates coaxially with the rotary encoder 2, which is set so that 200 pulses are generated per revolution.
Preset down counter 4 raised to 400 pulses to increase accuracy and set to 50 scales, for example.
is made to auto-return when it subtracts one count for one pulse and reaches "0".

For internal use, the "1" digit is provided as "0" to "9" and the "10" digit is provided as "0" to "9" on the board. When such preset down counters 4 and 5 subtract and detect "0" 6, it is relayed to the stepping motor control circuit 7, and further to the stepping motor drive circuit 8.
The stepping motor 9 is set to a step angle of 1.8 degrees with a 1-pulse signal, and the stepping motor 9 rotates once.
If it is 200 pulses, feed roller 1 installed coaxially.
The feed amount of one pulse of 0 is 0.2826 mm, and the feed amount of 8 pulses is 2.2608 mm.
