摘要:
The present invention relates to an apparatus and a method for detecting the ending-point of a bobbin thread for a sewing machine using a bar code, which is capable of alerting a sewing operator of his/her desiring bobbin thread remains when they are left enough to finish sewing under operation. The present invention of the apparatus for detecting the ending-point of a bobbin thread for a sewing machine using a bar code so as to sense the ending-point of a bobbin thread during a sewing operation, comprises a bobbin to wind a bobbin thread therearound and at least one bar code to indicate a position in the surface of a bobbin, of which the bar code is printed on one or both side(s).

An apparatus and method for separating strands of floss, string, thread or yarn from a bundle. One embodiment of an apparatus for separating strands of floss, string, thread or yarn from a bundle that consists of an attachment device (12) with low mass, low moment of inertia and low rotational air resistance that attaches to one end of the bundle (10). The opposing end of the attachment device (12) is connected to a swivel assembly (14). The opposing end of the swivel assembly (14) is attached to a rotational energy absorption device (16) with higher mass, higher moment of inertia and higher rotational air resistance. The rotational energy absorption device (16) is depicted in one embodiment as a bob. Other embodiments are described and shown.

A modular material supply system for an automated quilting machine having a variety of fill material supply devices, a cover material tick magazine, a fill laminator, and optionally a digital printer. The system is capable of selecting the desired cover and fill materials and supplying them continuously to a laminator to form a layered material, which is then fed to the quilting machine. The flexibility of the modular system reduces the need for system downtime to changeover component materials for producing different quilted products.

A continuous, automated method and apparatus for manufacturing pillowcases in which a hem is continuously formed along one longitudinal edge of an indeterminate length fabric, and the fabric is thereafter successively cut to length and folded, with the folded pieces being sewn along the side and end thereof to form successive completed pillowcases. The versatile method and apparatus of this invention is adapted for manufacturing pillowcases of the conventional folded hem style, as well as pillowcases of the attached hem and mock attached hem styles.
摘要:
A face mask comprising an elongated sheet of porous material having upper and lower longitudinal edges and transverse side edges. A line of stitches of elastic material is sewn to the material along both its side edges, and a length of elastic cord at each side edge is secured to the material by interweaving with the line of stitches thereat. A free intermediate portion of the elastic cord is formed between the ends at which the cord is interwoven with the stitches to the porous material, and the free intermediate portion forms an ear loop. The elastic material is sewn to the porous material and interwoven with the cord lengths while the porous material is taut so that when the porous material is relaxed, the elastic material exerts a pull on the porous material to gather and contract the material at the side edges. In the manufacture of the masks, the porous material is continuously withdrawn from a roll thereof by drive rollers and advanced through a sewing machine where the line of stitches is continuously sewn along each of the opposite side edges of the material while the material is taut. The cord is periodically interwoven along each side edge with the line of stitches, and a cutter downstream of the sewing machine cuts the porous material transversely thereof at successive spaced locations at which the cord is interwoven with the line of stitches.

A series of shirt cuff pattern parts are placed in overlying relationship on a web of lining material and a conveyor belt engages the upper surfaces of the web of lining material and the pattern parts and holds the layers of material together as they are moved through a sewing machine. The overlying side edge of each of the pattern parts is folded down under an edge of the web of lining material, and the sewing machine sews through the folds. A predetermined range of lengths of the connected together series of partially completed shirt cuffs is continuously accumulated from the sewing machine, and are continually fed from the accumulation to a cutter, and are separated by cutting the web of lining material adjacent the trailing edge of a pattern part so that each partially completed shirt cuff is formed with a short length of the web of lining material protruding from the shirt cuff panel pattern part, and the pattern parts are stacked.
摘要:
There is provided a draping conveyor having a narrow upper margin, a flatwork piece feeding means for feeding sequentially flatwork pieces to a draping station, and flatwork piece engaging means for engaging the flatwork piece at the draping station and pushing a portion thereof over the top of the narrow margin of the conveyor as the feeding means continues to operate, so the flatwork piece is draped over the conveyor with a fold located on one side thereof and the confronting portions thereof extending from the fold depending and both exposed on the other side of the conveyor. The draping conveyor is moved first to a sewing station on the opposite sides of which sewing machines are positioned so operators can readily grasp the exposed end portions of the flatwork piece delivered thereto and apply the same to their sewing machines simultaneously. The flatwork pieces fed sequentially to the draping station are formed from the unwound portion of a roll of flatwork piece forming material which is carried by said feeding means past a severance station. The feeding means is momentarily stopped to allow a severing means to move across the flatwork piece forming material to sever a flatwork piece from the end of the unwound portion of the roll of such material.
