  • Patent number: 5224361
    Abstract: Thread used in double-cylinder circular knitting machines is cut by locating a stationary cutting knife near a space between the cylinders. A saw having perpendicularly arranged teeth is positioned on an outer ring at the top of one of the cylinders. Thread guides move the thread from a pneumatic nozzle to the teeth of the saw. The saw engages the thread and moves the thread for knitting to needles on the cylinder. The saw continues to move the thread from the nozzle to the knife in order to be severed. After severing, the guide is returned and the thread engaged between the needles is disengaged and taken by the saw to the knife to be cut and taken in by the nozzle.

  • Patent number: 5211035
    Abstract: A method of making a sock especially adapted for use as a ski sock. The sock is designed to avoid sock pull down or drag down problems by utilizing a stabilizing band of elastic yarn knit in plated relationship with the body yarn and extending around the apex of the heel. The method of manufacturing this split-heel construction uses a circular hosiery knitting machine having short, medium and long butt needles. The needles are selectively lifted out of and dropped in to the knitting track of the machine to form the desired split-heel which prevents sock ride down.

  • Patent number: 5119643
    Abstract: An improved male-female type connector assembly. A male connector includes hook elements while a female connector includes a composite of a flexible substrate having a knit structure with loops produced about at least a portion of same. Loop weight, loop density and/or configuration of the hook elements may be varied to produce an assembly that is intended for repetitive connective, disconnect operations, or a semi-permanent structural connection.

  • Patent number: 5062183
    Abstract: The batt or sheet to be combed is unwound by rotation of a lap roller (1) from a lap disposed thereon. The batt goes from the lap roller (1) by way of the lap feed plate (13) to a feed cylinder (10) mounted in oscillating nippers (6, 8). The feed plate (13) is connected by way of its bottom edge to the oscillating nippers (6, 8) and by way of its top edge to an element (16) which is rigidly secured to the frame and disposed near the lap roller (1). The plate (13) is made of plastics and has a reduced thickness between the two edges in a linear bend zone (18) which is parallel to the edges. The bend zone (18) extends over the whole width of the plate (13) and acts as an articulation. The plate (13) is therefore simple and economical to produce. It requires no hinge between the two edges; also, it is of reduced weight.

  • Patent number: 5052088
    Abstract: In a textile warping system having one or more driven yarn engaging or yarn winding rolls, e.g. a driven warp beam, braking of each driven component is controlled by an individual pneumatic brake operated by a central programmable logic control system to brake the driven component according to a predetermined relationship of decreasing speed to elapsed braking time.

  • Patent number: 5044047
    Abstract: The can-filling apparatus for a textile machine comprises an upper part supporting a filling head, a lower part structured particularly as an automatic coiler-can exchanger, and at least one upright supporting the upper part and exctending between the upper and the lower part. The at least one upright constitutes a telescopic pair of columns structured such that the telescoping displacement of one column relative to the other column of the telescopic pair of columns is infinitely variable. The one column telescopingly displaced relative to the other column can be arrested at a selectable height and, is required, connected to the other column of the telescopic pair of columns.

  • Patent number: 5035027
    Abstract: An apparatus for manipulating the drafting roller carrier of a textile machine includes a handle for selectively maintaining the drafting roller carrier in an operative position in which the upper drafting rollers on the carrier are in nip engagement with the lower drafting rollers. The apparatus additionally includes an assembly for interconnecting the handle and the carrier for selected coordinated movement of the carrier and the handle upon manipulation of the handle between a handle operating position and a raised position. An operating stop device and a raised position stop device each include a concave surface and the handle includes a nesting member compatibly configured with the concave surfces to nest therein to prevent movement of the carrier from its respective operating or raised position.

  • Patent number: 4999881
    Abstract: A condensate control apparatus for receiving drum type condenser units utilized in cotton ginning which eliminates moisture buildup on predetermined metal surfaces within the condenser unit by heating such surfaces with heated dry air emanating from a heat source and conducted to such surfaces through a series of heating ducts. The condensate control apparatus also compacts the cotton gin fiber collected by such condensers into batts wherein the compacting force utilized in combination with moisturized air integrated within the cotton is sufficient to overcome the cottons inherent resiliency thereby permanently reducing the volume per unit weight of such cotton batts.

  • Patent number: 4984437
    Abstract: A driving mechanism (1) comprising first and second drive shafts (10, 22) respectively causing the movement, through first and second eccentrics (17, 24) of a needle bar (3) and one or several tube-bars (5). Also mounted on the drive shafts (10, 22) are auxiliary eccentrics (18, 26) which control the movements of respective counterweights (21, 28) in phase opposition relative to the oscillatory movements transmitted to the needle-bar (3) and tube-bars (5), in order to counterbalance the forces of inertia resulting from the reciprocating movements imparted to the bars (3, 5) themselves.

  • Patent number: 4964196
    Abstract: A coarse cleaning machine for textile fibres including a casing, a horizontal roller rotatably mounted in the casing, the roller being fitted with beater elements and bar grates are arranged on the underside of the roller. Located above and at one end of the roller is an inlet which carries delivery air for conveying the textile fibres in the form of flocks and an outlet is located above and at the other end for the roller. Deflectors which are inclined with respect to the roller axis are arranged above the upper side of the roller between the inlet and the outlet. The deflectors define transfer chambers which deflect the delivery air further in the direction of the axis of the roller. At least part of the transfer chambers are covered by a wall which is permeable to air and dust and a low pressure chamber connected to a suction pipe is located above the wall.
