Problems solved by technology

[0006] However, in the case of the above-mentioned conventional intermediate presser device, the height of the intermediate presser foot cannot be changed during the sewing operation.
Therefore, in order to adapt to the thickness of the material to be sewn, such as the thickness of the material to be sewn, it is necessary to adjust the above-mentioned swing member and adjust the height of the intermediate presser before sewing, resulting in a decrease in productivity.

Embodiment Construction

[0034] Next, an embodiment of the present invention will be described based on FIGS. 1 to 16 .

[0035] In this embodiment, an electric cycle sewing machine will be described as an example as a sewing machine. The electronic cycle sewing machine has a holding frame as a holding part, and the holding frame holds the cloth to be sewn as a sewing object, and when the holding frame moves relative to the machine needle, a shape is formed on the cloth held by the holding frame. Stitch based on specified sewing data (stitch pattern).

[0036] Here, it is defined that the direction in which the machine needle 108 described later moves up and down is defined as the Z-axis direction (up-and-down direction), and a direction perpendicular thereto is defined as the X-direction (front-rear direction). The direction perpendicular to both sides is defined as the Y direction (left-right direction).

[0037] Electronic cycle operation sewing machine 100 (hereinafter referred to as sewing mach...

Abstract

A seaming machine (100) can operate a needle (108) and a holding frame (111) according to a plurality of seaming pattern data composed of stitch data and stored in an EEPROM (72) and form the stitch relative to the stitch data. The seaming machine (100) comprises a middle press stand height adjuster (as controller (1000)) for adjusting the height of a middle press stand (29) of a cloth press (1) according to the middle press stand height stored with the stitch data of seaming pattern data. The invention can change the height of middle press stand at any time to realize effective seaming.

Description

technical field [0001] The invention relates to the control of a sewing machine with an intermediate cloth pressing device. Background technique [0002] In the past, in sewing machines such as cycle sewing machines and embroidery sewing machines, which hold the cloth by a frame-shaped pressing device and transport the cloth in the XY direction for sewing, in order to prevent the cloth from being twisted due to the friction between the cloth and the needle when the needle is raised, Sewing confusion caused by rising with the needle, so set the middle cloth pressing device. [0003] This intermediate cloth pressing device has an intermediate presser which moves up and down following the up and down movement of a random needle in a state of being pressed downward by an elastic force. Usually, the lower end of the intermediate presser foot touches the fabric when the needle is lowered. At this time, the state of pressing the fabric is maintained by the elastic force without fo...
