Abstract
The present disclosure relates to a method for controlling the position of a seam contour and a device for carrying out the method, wherein the position control of a seam contour relative to structures of a sewing material is based on comparison data of a structure of a reference sewing material and a structure of a working sewing material.
Claims4
A method, comprising:
- recording reference positions of sewing material structures by a reference sewing material having such structures;
- generating reference structure data sets based on the recorded reference positions;
- recording of working positions of sewing material structures of a working sewing material, which correspond to the sewing material structures of the reference sewing material,
- generating working structure data sets based on the recorded working positions,
- comparing the working positions with the reference positions by comparing the reference structure data sets with the working structure data sets,
- creating an adapted sewing program by adapting parameter data of the sewing program based on deviations between the reference structure data sets and the working structure data sets detected during the comparing step;
- and
- sewing the working sewing material with the adapted sewing program.

A sewing device (1), comprising:
- a sewing machine controlled by a sewing program,
- a sewing material frame (8),
- a camera system (9), and
- a programmable control unit (12), which is in signal communication with the sewing machine and the camera system,
- wherein the sewing device (1) is configured to perform the following steps:
- recording, with the camera system, reference positions of sewing material structures in a reference sewing material having such structures while the reference sewing material is held in the sewing material frame (8);
- generating, with the programmable control unit (12), reference structure data sets based on the recorded reference positions;
- recording, with the camera system, working positions of sewing material structures of a working sewing material, which correspond to the sewing material structures of the reference sewing material while the working sewing material is held in the sewing material frame (8);
- generating, with the programmable control unit (12), working structure data sets based on the recorded working positions;
- comparing the working positions with the reference positions by comparing the reference structure data sets with the working structure data sets;
- creating an adapted sewing program by adapting parameter data of the sewing program based on deviations between the reference structure data sets and the working structure data sets detected during the comparing step;
- and
- sewing the working sewing material by the sewing machine with the adapted sewing program.
