Definitions

  • Machines are already known for forming rolls from a strip of paper comprising at least one receiving mandrel and means for driving this mandrel in rotation to form the roll, means for cutting the strip of paper upstream from the roll when it has reached the desired dimension.
  • the object of the present invention is to increase the productivity of a machine, by reducing as much as possible the time necessary for fixing the rollers.
  • the machine which is the subject of the invention is characterized in that it comprises a mechanism for driving the roller in rotation after cutting the strip of paper; this mechanism being constituted by a roller arranged so as to bear against the outer layer of the roller and driven by a determined angle to bring the bor: end of the strip of the roller considered in position superimposed on the last layer of the roller and facing a dispenser of sticky coins arranged to apply a coin on the roll in order to fix the end edge of the strip to the last layer of the roll.
  • Roll forming machines are well known in themselves and include supports for one or more large diameter rollers, as well as means for slowing the rotation of these rollers, in order to obtain a regular tension of the strip which is unwound to wind on small diameter rolls.
  • the machine may also include devices for cutting the strip delivered by a feed roller and thus obtain several parallel strips of smaller width. Such machines are used in particular for making paper rolls for cash registers, telex devices, calculating machines, etc.
  • the terminal part of the roll forming machine comprises a mandrel holder 1, capable of rotating around a shaft 2 and provided with two rotary rods 3 and 3 'on which the mandrels which are cardboard tubes constituting the hollow central support of a roll.
  • the means for driving these rods 3 and 3 'in rotation are not shown, because they are well known in themselves.
  • a strip of paper 4 which may consist of several superimposed layers, is wound on the mandrel carried by the rod 3, while the mandrel holder is stationary.
  • a mechanism causes the mandrel holder 1 to rotate by 1 ⁇ 2 turn and the formed roller occupies position 3 '.
  • an end portion of this strip comes to occupy the position 4 'in which it rests on the mandrel of the roll to be formed and extends above a rail 5 of a cutting device, this rail 5 has a rectilinear groove 6 in which a cutting roller 7 engages and moves to cut the strip or strips passing over this rail.
  • This cutting device is not part of the invention and is therefore not described in detail.
  • the terminal part of the machine includes a device for terminating the rollers.
  • Device which enables an adhesive label or any sticky piece to be placed on the terminal edge of the tape roller.
  • this device comprises a frame constituting a receptacle for strips of self-adhesive labels carried by a support strip 9, originally, this support strip forms a roller 10 simply placed in the bottom of the receptacle 11.
  • the frame 8 carries an oscillating arm 12, articulated at 13 and subjected to the action of a jack 14 for controlling its pivoting, this arm 12 carries at least one roller 15 capable of being driven in rotation by an angle determined by a motor not shown.
  • roller 15 Above this roller 15 is a spout 16 over which the support strip 9 passes at an acute angle, before engaging with a toothed drive drum 17 which is driven by a stepping motor device. Due to the acute angle formed by the support strip 9 on the spout 16, each adhesive piece detaches itself from the support strip.
  • the drawing shows a coin 18 in the process of detaching and arriving near the periphery of the roller carried by the rod 3 '.
  • the portion bearing on the mandrel by the rod 3 is taken by means not shown and known to be held on the mandrel of the roll to be formed.
  • the roller 15 is driven by a determined value, which rotates the roll formed to complete the winding thereof.
  • the drum 17 is driven by a value corresponding to the distance separating two coins 18 on the support strip 9, so that the coin 18, in the process of detachment, comes to be applied partially on the terminal edge when entering it.
  • the roller 15 still continues its rotation by a value sufficient for the end edge with the piece 18 to pass between this roller and the formed roller, which applies this piece 18 to the peripheral layer of the roller which is then finished.
  • the jack 14 is then actuated to move the roller 15 away from the roll formed and thus allow the unloading of the machine. The user can then replace on the rod 3 'new mandrels which are thus ready to receive future rollers.
  • the mandrel mounted on the rod 3 can be rotated to form a roller. This operation can therefore be carried out at the same time as the operation for fixing the strip of the finished roll or rolls takes place.
  • the device delivering the coins 18 could be of any suitable type.
  • it could include a sizing device for non-adhesive plain paper fixing pieces.
  • the roller 15 - could be mounted to rotate directly on the frame 8, the latter then being displaceable by translation or by pivoting so as to be distant and respectively approaches the roller in position 3 ′ in this way, the distributor of tabs or labels 18, as well as the roller 15 can always be brought into a correct position relative to the roller in position 3 ', regardless of the diameter of the latter.
  • the stopping position of the assembly could be determined by the abutment of the roller 15 against the roller itself.
  • roller 15 and the distributor of tongues could be mounted stationary on the machine.
