Definitions

  • the present invention relates to the field of machines for winding strip material for making reels and relates to a device for cutting and applying, without glue, the start of strip of a new reel on a mandrel of a reel.
  • the winding of strips by means of winding machines generally poses the problem, on the one hand, of the cutting of the strip and, on the other hand, of the correct application of the end of the strip on the mandrel after the cup.
  • the cut is carried out manually by two operators, one of whom holds the end of the cut strip while the other glues the new mandrel, then applies said end to said new mandrel, the start of which is controlled by one of the two operators.
  • Such an embodiment requires, however, an intervention of the operators in a running machine, which necessarily entails a risk of accident.
  • strip materials require winding on the receiving mandrel without applying glue or adhesive tape, by simply pinching the first wound turns, with a view to their subsequent transformation.
  • Such a winding is particularly difficult to achieve, avoiding any risk of slipping when starting the winding in the case of winding relatively rigid materials.
  • GB-A-1 154 662 also discloses a device for cutting strips and winding the start of the strip on a new mandrel, in which said new mandrel is surrounded over most of its circumference by a shell. in two elements hinged together, the cutting action of the strip having the effect, in the continuation of the movement of the knife, of bringing the beginning of the strip in a corner formed for this purpose to the corresponding part of the shell.
  • this document GB-A-1 154 662 describes a first pivoting means partially surrounding the new mandrel and a second pivoting means for cutting the strip to be wound.
  • This second pivoting means consists, in fact, only of a serrated knife, extending over the entire width of the pivoting means and disposed at the end of a pressurized air box and tending to effect the introduction of the start of the strip into the shell formed by the first pivoting means, upon arrival at the end of the knife cutting stroke, this introduction being favored by air blowing.
  • the air blowing combined with a rapid rotation may not be of sufficient efficiency to avoid folding of the tips of the teeth.
  • DE-A-39 00560 describes a device for winding a strip start on a mandrel, this device consisting of a pair of prongs each provided with an articulated lever for partial closure, said prongs and their articulated levers being interconnected by shafts guided in rotation, on which are mounted parallel belts.
  • the device can be made to extend partially around the new mandrel, on which the strip must be wound, the belts being intended, on the one hand, to apply the beginning of the strip to the new mandrel, and, on the other hand, to guide it around said mandrel until at least one winding turn, this avoiding any turning of the end of the strip before or during the winding of the first turn.
  • This device does not, however, in any way provide a second means intended to perfect the introduction of the strip into the device, as well as its hold without crease during the realization of the first turn. In fact, no mobile means are provided which tend to follow the movement of the end of the strip to be wound.
  • US-A-4 326 679 discloses a device for cutting a strip and applying its end to a new mandrel, this device using lateral means for applying the strip to a large part. of the circumference of the new mandrel, as well as a means of cutting said strip.
  • transverse deflection means for the strip to be cut and wound.
  • additional means ensuring an additional tension of the strip during cutting, so that after said cutting occurs a tendency to the creation of slack on the corresponding part of the strip, which results in a random application of the end thereof on the new mandrel.
  • the present invention aims to overcome these drawbacks by proposing a cutting and application device making it possible to surround a new mandrel over the greater part of its periphery in order to favor the winding of a strip start following a section of said strip, this section being a straight, frank and not serrated section.
  • a device for cutting and applying, without glue, the start of the strip of a new reel on a mandrel of a reel essentially constituted by a first pivoting means of cutting the strip to winding and applying the end of the latter onto a new mandrel, without prior gluing of the latter, and by a second pivoting means for introducing, after cutting, the end of the strip into the first pivoting means and application of said strip on the new mandrel
  • the first pivoting means comprises a cross member for supporting a knife of transverse section in the form of a carriage guided on the cross member and actuated by a jack and cooperating with a transverse anvil also extending between arms forming a pivoting frame constituting the first pivoting means, said anvil forming a stop for a similar anvil fixed to the corresponding end nte of the second pivoting means, the cutting plane of the knife being preferably located near the axis of a fixed lower shaft for guiding and supporting a first pivoting means of cutting the strip to wind
  • the device for cutting and applying, without glue, the start of the strip of a new reel on a mandrel 1 of a reel consists essentially of a first pivoting means 2 cutting the strip 3 to be wound and applying the end of the latter on a new mandrel 1, without prior gluing of the latter, and by a second pivoting means 4 for introducing, after cutting, the end of the strip 3 in the first pivoting means 2 and of applying said strip 3 to the new mandrel 1.
  • the first pivoting means 2 is constituted by a pivoting frame formed by a pair of arms 5 extending parallel near the edges of the frame 6 of the winding machine, interconnected by a cross member 7 for supporting a cutting knife transverse 8 and each actuated by a jack 11 and by a first train of parallel elastic belts 9, endless, mounted on at least one pair of parallel shafts 10, guided in rotation, at their ends on the arms 5 ( Figures 1 to 3).
  • the parallel elastic belts 9 are preferably mounted on three shafts arranged in parallel so as to form a vertical section in a triangle, one of the sides formed by the belts 9 is elastically deformable by application against the mandrel 1 and whose one of the vertices, formed by one of the shafts 10, is displaceable by pivoting, by means of a pair of arms 12, represented in FIG. 3 by a simple axis line.
