Embodiment Construction

[0062] figure 1 is a cross-sectional view of rack 1. The frame 1 is formed from two U-shaped elements 2 , whose legs are aligned with one another, so that a box-like frame 1 is formed. On the frame 1, the drive shaft 3 extends parallel to the longitudinal direction of the needle head 1, the drive shaft 3 is fixed in rotation with the cam 4, and the cam 4 and the drive shaft 3 form a driver 5 for the needle 6, the driver 5 The drive shaft 3 moves in an oscillating manner, and the oscillating motion of the drive shaft 3 is converted into a translational motion of the needle 6 .

[0063] The needle 6 is arranged at a support element 7 capable of performing a translational movement by means of the drive 5 . The mounting support 7 is guided on guide elements 8 fixed on both sides of the frame 1, each guide element 8 has two legs 9, 10, the two legs respectively contain inner holes 11, the holes 11 are the same The shafts are aligned and have sliding bearings 12 fixed inside.

Abstract

The invention relates to a chain stitch sewing machine comprising stitch-forming sewing elements including at least one needle head (1) and needles (6) arranged on the needle head and at least one gripper shaft and gripper hooks arranged on the gripper shaft, wherein the needles (6) and the gripper hooks respectively form a sewing element pair and are driven in a manner such as to perform preferably chain stitches and especially double chain stitches in a sewing material arranged on a sewing material support, respectively using a needle thread and a gripper thread. To reduce the masses to be moved during the sewing operation, the invention provides that the needles (6) are indirectly or directly connected to the drive (5) and that at least one and preferably more needles (6) can be mechanically decoupled from the drive (5), so that the needle(s) (6) in a position decoupled from the drive (5) is(are) not moved in a translational fashion during the sewing operation and does(do) thus not pierce the sewing material.

Description

technical field [0001] The present invention relates to a multi-needle sewing machine, in particular a multi-needle chain stitch sewing machine, comprising a stitch forming element having at least two needles, at least one gripper shaft and a The gripper hook above it, wherein a needle and a gripper hook respectively form a pair of sewing elements, wherein the needle and the gripper hook are driven by the needle thread and the gripper thread, respectively, against the support set on the sewing material On the sewing material, preferably multi-layer sewing material for chain stitch, especially double chain stitch sewing. The invention also relates to a method for forming a sewing pattern on a sewing material, in particular a multi-layered sewing material, wherein an excess of sewing bodies is utilized, namely a needle and a gripper respectively, such that at least one needle thread Connected to at least one gripper wire to form a chain stitch, in particular a double chain stit...
