  • Patent number: 4406233
    Abstract: A sewing unit for withdrawing web material, of the knitted type, from a source, folding it and then seaming one side to place it in tubular form. The apparatus includes a triangle unit for folding the web material as it is received from its source and then advancing it into operative association with a tentering member about which it extends. From the tentering member the folded material is advanced to the sewing zone of a sewing machine and then advanced to a position whereat the tubular material is wound onto a take-up roll. An elongated bar member being selectively adjustable relative to positions inclined from a horizontal plane is adapted to engage and raise the lowermost portion of the folded material whereby it is caused to be displaced toward the machines line of sewing.

  • Patent number: 4305552
    Abstract: A beaming device for fabrics and in particular for very elastic fabrics is described which comprises a first pair of rollers (3,5) for entraining the fabric from a textile machine, a second pair of rollers consisting of a winding roller 13 around which the said fabric is to be rolled in rolls and driving roller 11. The second pair of rollers turn at a lower speed than the first pair. The winding roller is caused to rotate by the driving roller 11 which in turn is rotated by the entraining roller 3 of the first pair of rollers by means of a transmission comprising a speed controller. The driving roller 11 is arranged between the said first pair of rollers and the beaming roller 23. The fabric to be wound loses any deformation caused by the first pair of rollers when it goes through the part 2' between the two pairs of rollers.

  • Patent number: 4231142
    Abstract: In a band-cutting machine comprising a lower frame supporting a cloth-drawing mechanism, a control device for mechanically connecting the rotating parts of the machine, an upper rotatable frame positioned on said lower frame supporting a roll for cloth and a roller stretcher, the improvement which comprises a stop switch positioned on said lower frame, an actuator and a stretch detector carried on said upper rotatable frame, the detector actuating the stop switch through said actuator when the cloth is no longer in a stretched condition when passing through the roller stretcher.

  • Patent number: 4106715
    Abstract: A rolling-up machine for lengths of cloth destined for collar-cutting machines, comprising a rolling-up bar, motor to drive the bar, a cloth-drawing roll, motor to drive the roll, a mobile frame carrying fixed stretching bars and a bar carrying the cloth to be rolled up, the mobile frame being able to move transversally to the direction of unrolling of the cloth and continuously align the profile of one of the edges of the cloth roll corresponding to the head of the roll formed on the rolling-up bar, a cloth-stretching roll spaced from and parallel to the cloth-drawing roll and rotating in the same direction; a pair of idler bars seated below the stretching roll on the mobile frame; these idler rolls being pressed one against the other so as to press the cloth passing therethrough and cause a relative transverse sliding motion between the stretching roll and the cloth as a result of the movement of the mobile frame in response to variations of the width of the cloth as detected by sensitive means, the interac

  • Patent number: 4059874
    Abstract: An improved fabric cutting machine for cutting tubular fabric into strip form having simplified and manually controllable adjustment devices for selectively controlling the rate of withdrawal of the tubular fabric from its source, the desired width of the strip to be cut and for synchronizing the rate of rotation of the feed means for advancing the fabric to the cutting apparatus with the rate of rotation of that portion of the machine which supports the source of tubular fabric.
