Embodiment Construction

[0042] figure 1 A schematic view of a region of the sewing machine according to the invention is shown.

[0043] In detail, in figure 1 Firstly, the stitch plate 1 , the material presser foot 2 , the presser foot bar 3 and the head element 4 of the sewing machine are shown. The sewing product is arranged on the stitching plate 1 during the sewing process. A conveyor (not shown) can be arranged below the stitch plate 1 , which is designed to convey the sewing item after a stitch for a predetermined stitch length. Likewise not shown are needles, needle bars and transfer feet.

[0044] The task performed by the material presser foot 2 is to press the sewing item downwards in the direction of the stitch plate 1 and to hold it in place. Then, during triple delivery, the delivery foot enables the sewing item to be delivered evenly. Furthermore, the sewing item is kept taut so that a uniform stitch pattern can be obtained.

[0045] For this purpose, pressure is required which a...

Abstract

The invention relates to a sewing machine. The sewing machine has the following components: a stitch plate (1) on which an object to be sewn can be arranged; a material presser foot (2), which is configured to clamp the object to be sewn; and a presser foot lever (3) on which the material presser foot (2) is mounted. The sewing machine further comprises a spacer element (5), and the spacer element (5) is designed and arranged in such a way that the spacer element (5) specifies a minimum distance (h) between the stitch plate (1) and the material presser foot (2). Furthermore, the invention relates to the use of the spacer element (5) in a sewing machine for specifying a minimum distance (h) between the stitch plate (1) of the sewing machine and the material presser foot (2) of the sewing machine.

Description

technical field [0001] The present invention relates to a sewing machine comprising at least a stitch plate, a presser foot and a presser bar. Furthermore, the invention relates to the use of spacer elements in sewing machines. Background technique [0002] Sewing machines are often used to mechanically create seams. For example, sewing machines in the automotive sector are used to provide seams or decorative seams to leather objects. In particular, such seams or decorative seams are provided in vehicles such as vehicle seats, dashboards or door linings. The seams or decorative seams are here primarily also used as decorative elements which are intended to impart a high-quality appearance to the leather object or at least support such a high-quality appearance. [0003] However, this can only be achieved if the seam is applied to the leather object uniformly in appearance on the one hand and durably on the other hand without damaging the leather object or modifying the le...
