Abstract

The sewing agent (89) delivers instruction to start the sewing process and the thread retaining delivers instructions to implement a thread retaining. Sewing control (81) exercises operating control for series sewing, needle handling (by the vertical and the positioning mechanisms) and thread cutting and retaining. The thread holder comprises a thread catch member for seizing a front thread final part and an actuator (72) for moving the catch member to a front and rear position to the thread. A contriving preparation instruction input agent (83) delivers instruction and contriving preparation control (81) exercises operating control for adjusting the needle into a contriving position between a upper and lower dead center through the vertical mechanism and an operating control for withdrawing a mobile structure around a vertical path of the needle after receipt of the input of an instruction from the contriving input agents.

Description

technical field [0001] The present invention relates to a button sewing machine for holding the ends of sutures. Background technique [0002] Conventional button sewing machines have an up and down mechanism for driving the needle in the up and down direction, a button holding mechanism for holding the button below the needle, a positioning mechanism for relatively positioning the needle and the button, a cutting mechanism for cutting the suture, The suture holding device which holds the front end of the suture extending downward from the threading hole of the machine needle almost at the same time as the suture is cut by the cutting mechanism, the cloth holding mechanism which holds the cloth as the sewing object on the needle plate, And a motion control mechanism for performing motion control of each of the above-mentioned configurations. [0003] Moreover, if the operator inputs an instruction to perform sewing through the starting pedal, the needle and the button are p...
