摘要： A device controls the speed of needle movement in a sewing machine and thus the stitch length based upon the movement of a motion detection device relative to a reference surface. The formation of stitches by the sewing machine is controlled by detected changes in position of the detection device relative to the reference surface in connection with a predetermined stitch length setting and starting speed, set on either the detection device, an adapter or as part of the sewing machine control. The detection device may move together with the article being sewn while the sewing machine and reference surface remain stationary, or the detection device may move with the sewing machine while the article that is being sewn and reference surface remain stationary.

摘要： This invention comprises a means to control stitch length of household sewing machines when used on free-motion quilting frames. A sensor in the form of a computer mouse or a pair of sensors in the form of optical encoders is used to determine the translational speed of the set of carriages that hold the sewing machine. This information is sent to electronic circuitry that converts this information to an electrical resistance which is applied to the foot pedal control electrical connector on the sewing machine. When thusly applied, this resistance sets the rotational speed of the sewing machine. This invention achieves stitch length uniformity by maintaining the proper relationship between the input signal from the sensor or sensors caused by carriage translation and the output resistance to the sewing machine which controls its rotational speed.

摘要： A processing device for processing a sheet material with a pattern of the present invention is such as a sewing machine with pattern matching operation. The processing device has a detecting unit for detecting a color state of the pattern of the sheet material and producing a color state signal indicative of the color state. The processing device processes the sheet material on the basis of the color state signal produced by said detecting means. According to the present invention, the processing device is provided with an automatic adjusting unit for adjusting the detecting unit to allow the detecting unit to produce a desired color state signal with respect to a reference color state. Therefore, the white balance or the dynamic range is properly adjusted simply and reliably for the processing device.

摘要： Stitching coordinates prior to finish-up stitching are used to produce finish-up stitching data, resulting in undistorted stitching in all cases. Also, stitching data is pre-read out at start-up for stitching patterns continuously and predetermined stitching coordinates are obtained from the stitching data for making initiating finish-up stitching data. Therefore, it is no longer necessary to store the finish-up stitching data or the initiating finish-up stitching data in advance in a programming memory (ROM) so that operating efficiency of the sewing machine is increased.

摘要： The invention relates to a sewing machine provided with a needle reciprocated according to rotations of a main shaft and work feeding devices actuated synchronously with rotations of the main shaft, setting a margin to sew from a trailing edge to a sewing end position. The sewing machine includes devices for computing a terminal stitch length according to a set margin width. Control devices are provided for controlling a sewing to be carried out for coping with that which corresponds to the terminal stitch length computed by the computing device. The sewing machine further comprises computing devices for applying a correction to at least one of a number of stitches and a feed pitch, as occasion demands, where there arises the remainder as the result of an operation of the computing devices, and control devices for controlling the sewing to be carried out according to the computed result.

摘要： In an actuating mechanism for the hook of portable sewing machines, a hook actuating profiled cam is provided which has a pin for simultaneously actuating the hook and the material transport feed dog through an interposed linkage having an adjustable element. By providing the hook formed with an eye, a double chain stitch seam can be effected. By further providing the cam with a depression for accommodating a foot of the hook therein during an oscillation of the foot, a greatly reduced overall size becomes achievable. Thanks to the adjustable element it also becomes possible to change the stitch length.
