Abstract: The present invention provides a sewing machine enabling to sew a high-quality pattern without using an embroidery frame. In a sewing machine 1, a pattern is sewn while a fabric 100 is fed in a sewing direction by a feed dog 2a. The sewing machine 1 has a fabric guide 14. The fabric guide 14 has a guide portion 16 which extends straight in a sewing direction to serve as a basis of a cloth feed in an amplitude direction of the needle. The carriage 10 makes the fabric guide 14 slide in the amplitude direction of the needle by a predetermined distance. Thus, the guide portion 16 serves as an index of the position of the fabric 100 to be located for sewing the next pattern line. Since the fabric 100 can be accurately located for sewing the next pattern line, high-quality pattern can be sewn.

Abstract: Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. A technique includes determining a fabric's response to a laser, capturing an initial image of a wear pattern on a garment, and processing the initial image to obtain a working image in grayscale. The working image is further processed to obtain a difference image by comparing each pixel relative to a dark reference. The difference image is converted to a laser values image by using the previously determined fabric response to the laser.

Abstract: A sewing machine includes a sewing machine motor serving as a drive source for driving the vertical movement of a needle bar, a control part for controlling the sewing machine motor such that a sewing pitch coincides with a set value, and imaging part for imaging a seam formed in a workpiece at a needle drop position. The control part obtains the length of the most recent seam from an image of the most recent seam imaged by the imaging part and also compares the length of the most recent seam with the set value of the sewing pitch to thereby correct the number of rotations of the sewing machine motor.

The free surface is recessed relative to the outer face of the first broad side, whereby a distance between the recessed free surface and the outer face of the second broad side defines a reduced shank thickness which is less than the full shank thickness.

Abstract: In the production of multicolored yarn from differently colored filament bundles, the individual bundles may be texturized collectively. Then they are separated again into crimped part-threads 11.3 through 11.5 and are compacted individually in after-compacting means 8 before these part-threads are jointly compacted in a collective compacting means 9 and subsequently are wound up as a yarn 12 in a winding device 10.

Abstract: A machine makes tapered and also uniformly waved bristles for brushes, especially useful for paint brushes, by a method of applying uniform crimping pressure to crimp straight tapered bristles between two crimping gears (20, 30) having mating indentations. The spacing between the crimping gears is freely variable but the force is generally constant. This results in a wave amplitude that is constant over the length of each bristle regardless of the taper. The "floating" constant-force crimping pressure may be provided by weight biasing or electronic control. Tapered wavy filaments brushes employing such filaments and methods of forming such filaments also constitute a part of this disclosure.

Abstract: Three-dimensional knitted catalyst gauzes made from noble metals have recently come into use for ammonia oxidation and other gaseous reactions. Particularly high yields accompanied by a stable course of the reaction and an extended service life of the catalyst gauze are achieved if the catalyst gauzes are knitted in two or more layers and the layers are connected together by pile threads. Important features are the largest possible number of pile threads per unit area and the alignment thereof as parallel as possible to the direction of flow of the reaction gases.

Abstract: A knitting machine is described in which the elastic thread packages (26) are mounted in a stationary position away from the knitting head (22). This results in reducing the revolving mass and the space necessary to accommodate the revolving mass. Furthermore, the commencement of wind on the package (26) can be left as a tail which is knotted to the free end of a second package thus permitting the machine to run continuously without stopping to change packages. A plurality of like knitting heads (22) is mounted in relatively close proximity in a single knitting head frame (24) in such a manner that chain stitches are fed from a power driven warp beam (12, 16, 20). Each knitting head includes yarn positioning apparatus in which yarn (12) fed to each needle (30) of the knitting head (22) is moved under tension with minimal friction to a position where the needle (30) traps the yarn (12) on its downward stroke. Embodiments of the invention are described.
