Thread stand with vertical thread take-off and horizontal thread feed into the thread guide of the sewing machine for sewing machines with vertical thread spool holder

Abstract

Thread stand for attachment to a sewing machine with a vertical thread spool holder, characterized by - a mounting device for mounting on the vertical thread spool holder, - vertical storage of a yarn reel, - a first thread guide for vertically pulling the sewing thread upwards, - as well as additional thread guides that guide the thread in a deflection system back to the height of the thread reel, whereby the thread is transferred to the thread guide of the sewing machine at the height of the thread spool, to prevent the thread spool from rotating and to ensure even, tension-stable thread feed from the original direction.

Description

The invention relates to a yarn stand with integrated yarn guides as accessories for household and industrial sewing machines, in particular for optimizing the yarn feeding and for stabilizing the yarn tension.Prior Art:In many commercially available sewing machines, the yarn is drawn horizontally from a stationary yarn roll which is mounted on a vertical yarn package holder. The yarn roll rotates with it, which can lead to fluctuations in the yarn tension-especially in the case of larger or heavier yarn rolls. This can have a negative effect on the quality of the seam and the uniformity of the stitch pattern. Although external or mountable yarn stands exist, they typically do not return the yarn back to the original position of the yarn roll. As a result, the thread runs at a different angle into the first thread guide of the sewing machine, which increases the risk that the thread jumps out or moves non-uniformly.Object of the invention:The object of the invention is to provide a yarn stand which can be easily retrofitted and which enables uniform yarn feeding without twisting the yarn roll together, stabilizes the yarn tension and at the same time guides the yarn back to the original position of the yarn roll. The decisive difference from existing yarn stands is that the yarn is returned to the height of the yarn roll, so that the entry into the yarn guides of the sewing machine takes place from the same direction as in a classic yarn roll position. This reduces the risk of the thread jumping out of the thread guide.Solution:The invention provides a yarn stand which is fitted onto the existing vertical yarn package holder of the sewing machine. The yarn stand enables the vertical mounting of the yarn roll. The yarn is first drawn off vertically upward by a first yarn guide and then returned to the height of the yarn roll by two further yarn guides in a deflection system. This system prevents the yarn roll from being co-rotated and ensures a uniform, tension-stable yarn feed from the optimum position. The yarn stand is universally usable and does not require any structural changes to the sewing machine.The invention combines in particular the following features:fastening directly on the sewing machine via a simple plug connection to the vertical yarn package holder,vertical thread draw-off, whereby tension-weakening rotation of the yarn roll is avoided,returning the yarn to the yarn roll height, thereby ensuring a secure, angle-neutral entry into the yarn guide of the sewing machine.Advantages of the Invention:• Reduction of thread tension fluctuations• No twisting of the yarn roll• Simple retrofitting by placing on existing yarn package holders• Suitable for heavy or large yarn rolls• Improved seam quality by constant yarn travel• Reliable entry of the thread into the thread guide of the sewing machine by means of the correct guide heightList of reference characters1 Sewing machine 2 Vertical yarn package holder 3 Yarn stand (invention) 4 Yarn roll 5 First yarn guide (vertical draw-off) 6, 7 Further yarn guides (return to yarn roll height) 8 Yarn course

Claims

Yarn stand for attachment to a sewing machine with a vertical yarn package holder, characterized a receiving device for mounting on the vertical yarn package holder, a vertical mounting of a yarn roll, a first yarn guide for vertically pulling the sewing thread upward, and further yarn guides which guide the yarn back to the height of the yarn roll in a deflection system, wherein the yarn is transferred at the yarn roll height into the yarn guide of the sewing machine in order to prevent the yarn roll from rotating along and to ensure a uniform, tension-stable yarn feed from the original direction.
