Abstract: A unitary sinker finger is attached at its first end to a sinker bar. In a first embodiment the second end of the finger is attached to a fixed support member. The sinker finger has a loop formation region and a loop cutting region disposed thereon, with the loop cutting region being disposed intermediate the loop formation region and the second end of the finger. A cutting blade that is operable in the cutting region for cutting pile loops formed on the loop formation region of the finger. In a second embodiment the sinker finger is an arcuate member that cantilevers from the sinker bar. A loop cutter cooperates with the arcuate sinker finger to cut the pile loops formed on the finger at a location adjacent to the free end of the finger. A sensing arrangement for determining operability of the cutting arrangement is also disclosed.

Abstract: A method of knitting an elastic drawcord product and an elastic band and drawcord composite product are described. The method involves knitting a pair of elastic webs in a laterally spaced relationship to each other, and securing a drawcord within the space between the elastic webs by way of first and second tying yarns. The first tying yarn reciprocates across the space between the first and second elastic webs and is alternatively secured to the side edges thereof along the front face of the elastic webs. The second tying yarn reciprocates across the space between the first and second elastic webs and is alternatively secured to the side edges thereof along the rear face of the webs, and the drawcord is secured between the two elastic webs and the first and second tying yarns.

Abstract: A necessary number of knitting needles are slid at a predetermined timing along a multiplicity of parallel sliding grooves of a single needle bed, and a predetermined number of knitting yarn guides take lapping movements to form desired stitches of the knitting yarns while a monofilament bending means between one end of the needle bed and the yarn guides is operated at a predetermined timing for reciprocating along a predetermined number of knitting yarns at an underlapping position. During this reciprocating movement, a head-portion-holding member is moved between a holding position for holding a head portion of each fastener element from an inside thereof and a non-holding position, in synchronism with the bending of a monofilament.

Abstract: A knitting machine and method for forming a composite band including an elongate knitted band and a drawcord secured to a front face of the knitted band by a covering yarn overlying the drawcord and stitched to the elongate band. The knitting machine includes a frame. A first knitting station is provided supported by the frame for forming the elongate knitted band. A second knitting station is provided supported by the frame and downstream of the first knitting station for receiving the knitted band after it exits the first knitting station. The second knitting station is operative to stitch the covering yarn to the knitted band from opposite sides of and across the drawcord to form a channel area defined between the covering yarn and the front face of the knitted band, the drawcord disposed in the channel area.

Abstract: A pile forming warp knitting machine having a spaced plurality of needles and a pair of separate sinker assemblies. These sinker assemblies have a plurality of pile sinkers and a plurality of enclosing, knock-over sinkers. Both pluralities of sinkers are interdigitated with the needles. The pile sinkers each have a distal edge and a proximal edge. The knock-over sinkers each have an enclosing recess. The knock-over sinkers also have (a) an exposed first segment with a knock-over edge, (b) a second segment integral with the first segment, and (c) an enclosing nose integral with the second segment and having an inside edge extending alongside the second segment at a predetermined distance therefrom. In a first working mode the knock-over sinkers reciprocate relative to the needles between an enclosing position and a knock-over position. The enclosing position is at the enclosing recess. The knock-over position is external to the enclosing recess.
Abstract: An elastic band is fabricated with an integrated drawcord utilizing a crochet-type warp knitting machine by initially knitting a finished elastic band and, then, re-routing the finished band back through the knitting machine to a second knitting location at which fabric piercing needles are utilized to knit additional warp and filling yarns while a drawcord is simultaneously fed between the piercing needles to form a covering web over the drawcord defining a tunnel area between the covering web and the finished band in which the drawcord is captured.
Abstract: A stitchbonded absorbent article and method of making same are presented. The article exhibits good hand, repeated washing durability, and absorbency. The article includes first and second layers which are mechanically held together by stitches of yarn, at a stitch density ranging from about 15 to about 35 st/10 cm, and stitch gauge ranging from about 10 to about 40, using a stitching yarn comprising at least two compositionally different fibers having different heat stability being at least partially melt-bonded together at points of mutual contact, the yarn being melt-bonded at least partially to outer surfaces of the article.

Abstract: This section element has a cross-sectional shape with reentrant or inside angles and/or concave parts or a hollow polygonal or other shape. A plurality of parallel threads are held taut and maintained in the longitudinal direction of the section element in a configuration which corresponds to the cross-sectional shape of the desired section element. These longitudinal threads are progressively displaced continuously in front of a group of knitting heads knitting in two dimensions which are orthogonal and perpendicular to said longitudinal threads. Each knitting head comprises a plurality of series of needles I, L1, L2, LA, A1 and A1' each of which covers a specific portion of the cross section of the section element.

Abstract: The machine is of the type comprising rods defining the volume of the section element and extending in the longitudinal direction of the latter and a knitting head depositing threads around the rods in a direction perpendicular to the latter. The rods are thin hollow rods (12). A die (9) maintains the hollow rods in a fixed position parallel to each other in a configuration which corresponds to the cross-sectional shape of the desired section element. Feed devices (7, 8) feed the longitudinal threads of the section element through the hollow rods (12). A device (15) is provided for retaining one end (12a) of the threads issuing from the rods in an identical configuration. Two knitting heads (16, 17) of known type deposit threads in two planes which are orthogonal and perpendicular to the rods (12) in the vicinity of the ends of the latter. Devices (15, 5) are provided for continuously displacing the threads issuing from the rods as the threads are deposited by the knitting heads.
