Definitions

  • This invention patent discloses improvements to the machinery used for uncoiling pieces of fabric material from a roll or reel.
  • the machines used for laying out material from rolls on to a table for operations such as folding ,etc. comprise generally a long table with guides for defining the movement of a carriage which takes up the full width of the table and which supports the roll of textile material so that it can be laid out on the table in a controlled manner and be submitted to various manipulations.
  • the said carriage comprises the means of holding the roll in such a manner that it can be unrolled and also the mechanism for unrolling and guiding the piece, starting and stopping the movement on the table, etc.
  • the carrying unit incorporates a cutting device on its forward end such that apart from unrolling the material and laying it out on the table the machine has the means for transverse cutting the material to a required length, the cutting mechanism having transverse guides for its displacement and for other ancilliary devices.
  • the said jets have a predetermined angular orientation with respect to the longitudinal axis of symmetry of the piece of fabric such that the jet flow for optimum effect should be inclined towards the nearest outer edge of the material, so requiring that the jets be divided into two groups with one group located between the centre of the piece and one of the edges and the other group between the centre of the piece and the other edge or border of the piece of fabric.
  • the angle is not critical and can be from 15 to 60° to the longitudinal axis of the piece with a preference for 30 to 45°.
  • the air outlet stream while retaining part of the directional vector of the velocity reached in the distributor tubing has a transverse component with respect to the fabric piece, towards one or other of its edges, thus resulting in a satisfactory arrangment using simple and economic means
  • the angle between the air jet nozzles and the fabric material guideplate should be small thus forming an air cushion in the contact zone betweent the textile and the guide plate, so reducing the rubbing friction.
  • other angles of inclination to the guide plate can be effective but with an optimum within the range of 0 to 45°, and preferably between 0 and 15°.
  • Figure 1 shows a cross-section in schematic form of the roll support assembly and the draw out towards the guide plates.
  • Figure 2 is also a schematic view showing the frontal aspect of the roll carriage with a front view of the cutting device.
  • Figures 3 and 4 are respectively schematic views in section and in perspective of the cutting unit which is incorporated in the machine carriage.
  • these improvements apply to the mobile carriage of the machine for drawing out the pieces or rolls of textile material, as in current practice, thus it is not described in full detail but shown simply as as piece or roll of textile material -1- resting on endless belts -2- and -3-, the number being variable and motorized so as to cause the rotation of the roll -1- supported freely by motorized belts on the upper shafts -4- and -5-, the lower shafts -6- being common.
  • the orifices or nozzles -9- are distributed preferably along the whole length of a distribution block -10- which for preference is fed from a blower -11- or other centrally situated low pressure air system through the manifold -12-.
  • Figure 2 shows the air nozzles arranged such that they are in two groups with respect to the central line of symmetry -15- of the textile, represented by vectors in this figure, such that each group is orientated to provide a stream component towards its respective nearest side or border -13- or -14-.
  • the disclosures herein include also the disposition of a compensating air flow admission -16- , preferably being at atmospheric pressure having free access to the interstice between the piece of textile material -7- and the guide plate -8-, so as to compensate for local depression effects, particularly any venturi effect.
