Definitions
- the invention relates to a sewing machine according to the preamble of Claim 1 (see document US-A-5 025 738).
- Thread path pulling devices are used in which the needle thread end not by a mechanical thread wiper, but by one Compressed air flow moved out of the area of the presser foot becomes.
- a thread path pulling device is, for example, by US 3,371,632 is known.
- Such facilities are opposite Mechanically acting devices disadvantageous in that they are resistant and possibly also twisty threads u. U. only insufficiently pulled out of the area of the presser foot can and the facilities also have a comparatively high Compressed air and thus energy consumption.
- the invention has for its object a thread pulling device to create that both when processing thin and from particularly thick material can be used without restriction.
- the task is solved by the characterizing features of claim 1.
- the invention is based on the idea that the needle thread end by the the pin can be moved across the path of the needle thread just as far through the To withdraw the eye of the needle that on the one hand the presser foot at Do not lower the thread end between yourself and the material can and on the other hand the thread hanging from the eye of the needle a sufficient length for the perfect thread linking Has the beginning of the next sewing process.
- There is a essential prerequisite for the secure thread linking is that the withdrawn amount of thread is released before starting sewing again and is thus available as a free thread reserve.
- the sewing machine has and in a manner known per se movable needle bar 4 with a thread-guiding needle 5, one Thread feeder 6, a thread tensioning device 7 and one between one Rest and a pressure position up and down movable presser bar 8 with a presser foot 9.
- a gripper 10 cooperating with the needle 5 and one Thread cutting device 11 arranged.
- the arms are designated 14 and 15.
- the arm 14 is in drive connection with a compressed air cylinder 16, by a hinge pin 17 which is attached to the piston rod in a Clevis 18 is received in a slot 19 of the arm 14 intervenes.
- the air cylinder 16 is angular Carrier 20 arranged, which in turn by means of screws 21 on the head cover 3 is adjustable in height.
- a transverse thread retraction pin 22 attached, the free end is formed into a thread eyelet 23.
- the Air cylinder 16 and the angle lever 13 together form one Thread travel device 24.
- the angle lever 13 between one in solid lines shown rest position and a dash-dotted line Functional position can be pivoted back and forth.
- In this position runs from the Thread feeder 6 coming needle thread 27 substantially straight from the upper thread eyelet 25 through the thread eyelet 23 of the thread retraction pin 22 through to the lower thread eyelet 26 on the needle bar 4.
- the angle lever 13 remains in its rest position during sewing. It is only at the end of a seam after thread trimming effective thread tensioning device 7 of the compressed air cylinder 16, thereby moving the angle lever 13 from the rest position into the Function position pivoted.
- the thread retraction pin moves 22 transverse to the path defined by the two thread eyelets 25, 26 of the needle thread 27, thereby making it angular as shown in FIG. 1 undresses. Since here the needle thread 27 in the thread tensioning device 7 is held frictionally, the thread retraction pin pulls 22 thread through the thread eyelet 26 of the needle bar 4 and not closer designated eye of the needle 5 against the normal thread take-off direction back and in this way shortens that which hangs out of the eye of the needle Thread end.
- the position of the rest and the functional position of the angle lever 13 so that the Length of the shortened needle thread end has an optimal dimension, d. that is on the one hand it is short enough not to lower the presser foot 9 on a new workpiece between the presser foot 9 and the material to be pinched and on the other hand for the safe Thread linkage at the start of a new sewing process is long enough. It is of great importance that before the beginning of the next Sewing process of the angle lever 13 pivoted back into its rest position so that the thread quantity previously withdrawn is now available as a free thread reserve is available.
