Definitions

  • the present invention refers to a device for enlarging and straightening the structure of a fabric.
  • the prior art shows devices that take care of enlarging a fabric and removing small longitudinal pleats by using cylinders with staves.
  • These cylinders are equipped on their external surface with a plurality of staves arranged longitudinally to the rotation axis of the cylinder itself and able to slide according to an alternative movement controlled by two flanges arranged diagonally to the cylinder ends and aimed to guide the alternate and symmetric movement of the staves themselves.
  • the prior art provides for more or less efficient devices.
  • machines equipped with at least two idle wheels with pins keyed onto a transmission shaft, through which a transverse tension with respect to the weft direction is applied to the fabric, due to the relative speed change that can be generated between the two wheels.
  • Object of the present invention is solving the above prior-art problems by providing a device that allows simultaneously performing both functions of enlarging and straightening a textile structure in order to enlarge the fabric and correct possible weft distortions of the fabric weft itself.
  • Another object of the present invention is providing a device that can be easily arranged next to any textile machine in order to supply such machine with a fabric whose distortions have been corrected a few seconds before, without thereby giving them time to be formed again.
  • the device 1 is composed of a carrier axle 10 on which a first roller 2 and a second roller 3 are keyed-in side by side, each roller 2, 3 being equipped on its external surface with a plurality of staves 4, 6 that are sliding along the direction parallel to the longitudinal axis of the rollers themselves, and with a plurality of fixed staves 5, 7.
  • the rollers 2, 3 are keyed-in onto the carrier axle 10 so that the respective fixed staves 5 and 7 are side by side, while the sliding staves 4 and 6 can, during their movement, be partially extended outside the surface of their own roller 2, 3.
  • Each sliding stave 4 slides along the same direction of its own homologous stave 6 but along the opposite sense; such alternate symmetric sliding movement of the staves 4 and 6 is caused by two lateral rotating flanges 8, 9 that are symmetrically slanted with respect to the rotation axis of the carrier axle 10, arranged at the two end sides of the rollers 2, 3 and to which the sliding staves 4 and 6 are respectively connected, at one of their ends.
  • Each roller 2, 3 further cooperates with the carrier axle 10, by interposing at least one free wheel 11, 12 for each roller 2, 3.
  • the fabric 13 is inserted onto the rollers 2, 3 that are rotated by the sliding movement of the fabric 13 itself, imposed by the working process.
  • the connection of the sliding staves 4 and 6 to their respective slanted flanges 8, 9 generates an alternate symmetric sliding movement of the staves 4, 6 themselves that generates an enlarging effect of the fabric 13.
  • the free wheels 11 and 12 allow the two rollers 2, 3 to rotate independently one from the other but along a single direction. In this way a relative speed can be created between the two rollers 2, 3 that generates a transverse tension to the weft, creating a straightening effect for the threads of the weft itself.
  • the straightening effect efficiency according to the present invention can be increased by placing upstream (or downstream) of the device 1 a known adjusting cylinder 14; such adjusting cylinder 14 is a rotating roller that is free of assuming different slants and is able to supply the fabric 13 to the device 1 removing possible excessive tensions on the fabric caused by the straightening effect itself.
  • This adjusting cylinder 14 is hinged with two degrees of freedom and, in another possible application, can be adapted to also perform the function of a dancer cylinder, thereby saving parts and costs when manufacturing the device of the invention.
  • the device 1 according to the present invention in another preferred embodiment, can be coupled with a motor 15, for example an electric motor, aimed to rotate the carrier axle 10; in this way it is possible to control the longitudinal tension of the fabric 13 without impairing, due to the presence of the free wheels 11, 12, the freedom of independent movement of the rollers 2, 3.
  • a motor 15 for example an electric motor, aimed to rotate the carrier axle 10; in this way it is possible to control the longitudinal tension of the fabric 13 without impairing, due to the presence of the free wheels 11, 12, the freedom of independent movement of the rollers 2, 3.
  • the device 1 due to its reduced encumbrances and to the different functions that distinguish it, can be easily arranged upstream, downstream or integrated with any other textile machine in order to be able to always guarantee, in any working phase, an efficient straightening of the fabric and the absence of pleats and weft distortions.
