Definitions

  • the present invention relates to a machine intended for carrying out industrial operations, such as cutting or gluing, on continuously moving webs of complexes, intended in particular for the manufacture of respiratory filter masks or hygienic layers.
  • a second technique which consists of immobilizing the sheet only at the workstation by means of a device, not modifying the tension of said sheet nor the speed of travel of the parts thereof located respectively upstream and downstream of said post, constituted:
  • a first web return roller movable in space, driven by an alternating translational movement, associated with two other return rollers of said web, fixed in space, located respectively upstream and downstream of the first roller, in a plane distinct from that occupied by said first roller;
  • another first web return roller movable in space, driven by an alternating translational movement, associated with two other return rollers of said web, fixed in space, located respectively upstream and downstream of the first roller, in a plane distinct from that occupied by said first roller.
  • the invention aims to implement, in the case of said second technique, an alternative solution for the purpose of simplifying the device for immobilizing the web.
  • said device is essentially characterized in that the upstream rollers and the downstream rollers are located on either side of the plane formed by the parts of the web located respectively upstream and downstream of the workstation and in that that the rollers, which are driven by an alternating translational movement, are driven simultaneously in the same direction by means of a single support to which they are attached, which support is itself driven by a cam whose contour is adapted to communicate to him the movement of alternative translation.
  • said device for immobilizing the sheet which is of simple design, simultaneously drives, in the same direction, in full synchronization, the two rollers.
  • the contour of the cam comprises:
  • a second portion whose profile is defined to avoid blows during the passage of said portion of the web from the immobile position to the moving position and vice versa.
  • FIG. 1 is a schematic view of the device according to the invention.
  • - Figure 2 is a front view of the cam according to the invention highlighting its different portions;
  • - Figure 3 is a detailed view, in perspective, of the essential parts of the device according to the invention integrated in the workstation of the machine.
  • the device represented in the figures is adapted to be integrated with a machine intended to carry out, at a workstation (1), industrial operations, cutting or gluing types, on webs of complexes (2) running continuously. and intended primarily for the manufacture of respiratory filter masks or hygienic diapers.
  • Said workstation (1) comprises a device (3) able to immobilize, for a definite time, the part (21) of the complex web (2) located in the operating zone of said station, without modifying the tension of said tablecloth nor the speed of scrolling parts (22) and (23) thereof respectively upstream and downstream of said station.
  • Said device (3) consists of:
  • the upstream rollers (31, 32, 33) and the downstream rollers (34, 35, 36) are situated on either side of the plane (P) formed by the portions (22) and (23) of the sheet (2 ) respectively upstream and downstream of the workstation (1).
  • rollers (31) and (34), which are driven by an alternating translational movement (T), are driven simultaneously in the same direction by means of a single support (38) to which they are attached, which support is itself driven by a cam (37) whose contour is adapted to communicate the reciprocal translation movement (T).
  • connection between the cam (37) and the rollers (31) and (34) is carried out by means of a roller
  • the cam (37) is integral with the fixed support (40) or an extension thereof.
  • rollers (32,33,35,36) are fixed to fixed supports (40), in particular of the common platinum type.
  • the cam (37) is integral with the fixed support (40) or an extension thereof.
  • the contour of the cam (37) comprises:
  • a first portion (371) whose profile is defined according to the duration of immobilization of the portion (21) of the web (2) in front of the work station (1); - A second portion (372) whose profile is defined to avoid blows during the passage of said portion (21) of the web (2) from the stationary position to the moving position and vice versa.
  • R 0 the radius at the beginning of the ramp and ⁇ the radius angle R with respect to R 0 .
  • the device (3) able to immobilize, for a definite time, the part (21) of the complex web (2) situated in the zone of the workstation (1) can be doubled, or more, by means of:
  • rollers (311) and (341) are integral with the movable support (38) or an extension thereof.
  • the rollers (321) and (361) are integral with the fixed support (40) or an extension thereof.
