Definitions

  • the present invention relates to a method of cutting a non-woven textile web in a method of winding said web around a spinning driven reel.
  • the winding process consists in winding a non-woven fabric strip around a so-called receiving spool driven in rotation.
  • the method according to the invention thus relates more particularly to the cutting of the textile web, upstream of the receiving coil, to allow for example the evacuation of said receiving coil once the winding is completed.
  • the invention finds particular advantageous, but not limiting, application in a splicing process, or else slicing for example, when it is appropriate, at the end of winding, to cut the textile strip to change the receiving coil.
  • the method according to the invention is adaptable to any machine or any process in which it is necessary to cut a textile strip upstream of a receiving coil.
  • the invention also relates to a module for cutting a non-woven textile web in a process for winding said web around a rotationally driven reception roll.
  • the method allows to cut the textile strip upstream of the receiving coil. Since the method provides for a step of moving the precut line, the end of the strip not attached to the receiving coil is, once the cut strip, easily recoverable for another use, such as for example for the attach to a new receiver and continue the winding process. Stopping the unwinding of the strip to make a precut line, instead of a cutting line, then restart the unwinding to move the precut line, allows the cutting method according to the invention to be adapted to any type of winding process, such as a winding by slicing for example.
  • the tension-controlled winding of the strip is done by rotating in rotation, at a controlled speed, the receiving coil so as not to cause the cutting of the strip.
  • the cutting of the textile strip is performed, on the one hand, by blocking the strip upstream of the precut line and, on the other hand, by exerting a pull downstream of said line of precut, Blocking and traction are carried out by any appropriate means.
  • the strip is thus cut quickly and cleanly along said precut line, without the intervention of an operator.
  • the band is blocked when the precut line is out of the means that made it possible to make said weakening line.
  • said means having made it possible to produce the precut line does not interfere with recovering the portion of the upstream band.
  • the step of exerting a tensile force on the web consists of continuing the rotational drive of the web.
  • the process is simple and reliable.
  • the method according to the invention also comprises, after the cutting of the strip, a step of applying a compression arm to the width of the receiving coil, while continuing the rotational drive of the receiving coil to controlled speed and over at least one turn to compress the free end of the textile web against the spool.
  • a compression arm to the width of the receiving coil
  • the receiving coil will not run unexpectedly.
  • the essential point lies in the fact that the precut line must allow the cutting of the strip when it is blocked upstream of said precut line and that a force of traction is exerted on the strip downstream of said line.
  • the step of applying a compression arm consists in applying a transverse roller.
  • the transverse roller makes it possible to apply a controlled pressure over the entire width of the spool for compressing the free end of the strip against said spool and allowing its temporary "sticking".
  • the invention also relates to a cutting module of a non-woven textile web in a method of winding said web around a reception reel entrained therein as defined by claim 5.
  • the means capable of blocking the web tape can have different shapes.
  • the bottom line is that they are able to block unwinding of the tape.
  • These may for example be in the form of actuatable means for gripping the band.
  • the fact that these means are operable to come to pinch the band allows to pinch said strip upstream or downstream of the precut line according to the desired implementation of the invention.
  • the clamping is advantageously carried out over the entire width of the strip.
  • the clamping means are, for example, able to carry out a pressure on the strip against a surface.
  • the clamping means are thus operable to move from a neutral position in which they do not interfere with unwinding of the band at a clamping position in which they are resting against the band to pinch it against a counter surface and prevent its unwinding.
  • the pre-cut means are of all appropriate forms.
  • the essential lies in the fact that they are able to achieve a transverse precut line of the textile strip, allowing it to be subsequently cut along this precut line.
  • Means capable of exerting traction on the strip may have different shapes.
  • these are constituted by the means for rotating the reception coil, already present in the winding process of the strip.
  • the precut means are in the form of a blade comprising a sawtooth profile, or they may be in the form of a line of perforation needles capable of producing a perforation line, transverse, weakening the textile band.
  • the invention relates to a method and a module (1) for cutting a web (2) of non-woven fabric in a method of winding said web (2) around a spool (3) for receiving rotated .
  • the method and the module (1) according to the invention allow to cut transversely the strip (2) upstream of the coil (3). This operation allows the evacuation of the coil (3) once the winding of the strip (2) completed.
  • the winding process thus uses a receiving coil (3) to which is attached one of the ends of a strip (2) to be wound.
  • the spool (3) is rotated about its axis of revolution to wind the web (2).
  • Return rollers (4) are used to tension the web (2) and to return said web (2) to the web (3).
  • pre-cutting means (5) are arranged upstream of the receiving reel (3), and on the unwinding path of the textile web (2). These precut means (5) may have different shapes. These pre-cutting means (5) are movable from a first position in which they are not in contact with the band (2), to a second position in which they are pressed against the band (2), against the support against a surface (5b) for example, and over its entire width so as to achieve a transverse precut line (8) of said strip (2).
  • these precut means (5) are for example in the form of a blade (5a) comprising a sawtooth profile and subject to displacement means such as a jack (5c) for example.
  • the blade (5a) is pressed against a surface (5b) comprising a complementary sawtooth profile.
  • the winding of the textile web (2) is restarted.
  • the spool (3) is rotated again and at a controlled speed so as to wind the web (2) of textile around said spool (3).
  • This operation must be done at controlled speed and tension so as not to generate too much tensile force on the strip (2) which could cause its cutting along the line of weakness.
  • the winding thus causes the displacement of the precut line and the winding is continued until this line reaches a desired position.
  • the desired position is defined so as to leave the precut line of the congestion generated by the embrittlement means (5) so that once the subsequent cut made, it is easy to grasp the end of the strip (2) of textile not attached to the reel (3) receiving, that is to say the end of the strip (2) from said precut means (5).
  • clamping means (6) are arranged upstream of the coil (3) reception. These clamping means (6) are arranged such that they are able to block unwinding of the textile strip (2) upstream of the precut line. Thus, when the precut line has reached the desired position, the clamping means (6) are actuated and clamp the web (2) of textile, while continuing the rotational drive of the coil (3).
  • the clamping means (6) are thus operable to move from a neutral position in which they do not interfere with unwinding of the band at a clamping position in which they bear against the band (2) to pinch it against a against the surface and prevent its unfolding.
