Abstract

The invention provides a controller of sewing device, which is to make uniform the tension of a belt-shaped object sent into a sewing means, to prevent the enlargement of the size of a sewing machine and further to facilitate maintenance. Synchronously with the sewing movement of the sewing means 25, a sending-in driving means 27 and a supply driving means 29 are controlled by one control circuit 47. Therefore a sending-in means 26 and a supply drive means 28 can be controlled synchronously with the sewing movement, in correlation with each other. According to this constitution, it is possible to prevent a change in the tension of the belt-shaped object 23 between the sending-in means 26 and the supply means 28 due to the individual operations of the means 26 and 28, to prevent a change in the tension of the belt-shaped object 23 sent into the sewing means 25 due to the change in the tension between the means 26 and 28 and to maintain the tension to be uniform substantially.

Description

technical field [0001] The present invention relates to a control device for controlling a sewing device which sews a ribbon to clothing material. Background technique [0002] Figure 10 A block diagram showing a control device 1 in a conventional sewing device. The control device 1 is provided on a sewing device 2 for sewing a tape to clothing material, and is a control device for controlling the sewing device 2 .
