  • the dual tracking roll train 24 includes a second roll 26 providing tracking which is applied tangentially to the first roll 25 and which, for example, consists of a highly rigid roller which is chrome plated on its outer surface to resist abrasion and to provide optimum film spreading.
  • Rolls 25 and 26 rotate idly, i.e. are non-driven, on their corresponding end bearings.
  • end portions 25b and 26b of these two rolls are journaled in these end bearings at one of the ends of the rolls; the bearing ends 28a and 30a of the two rolls can be seen in figure 3.
  • the end bearings of rolls 25 and 26 are not directly carried by the sliding carriers supported on the linear guides but rather via pivoting arms 27 to 30, one end of which carries a bearing for a roll (roll 25 being carried by arms 27 and 28 and roll 26 by arms 29 and 30), and the other end of which pivots on one of the sliding carriers (19a and 19b for arms 27 and 28 and 20a and 20b for arms 29 and 30).
  • the two sliding carriers of a given roll are movable along two corresponding linear guides 19 and 20, which are arranged parallel to each other on the two vertical plates 17 and 18. These sliding carriers that support the arms are advanced and retracted while sliding along their relevant linear guides, by lead screws running parallel to the linear guides, rotation of which causes the carriers to advance or retract.
  • the displacement of the two sliding carriers of a given roll are mechanically synchronized by synchronizing means that link the two sliding carriers.

  • the rolls 25 and 26 are biased by their corresponding pivoting arms 27, 28 and 29, 30 for urging them respectively onto roll 5 and roll 25 by swinging the pivoting arms in the clockwise direction by the application of force from urging means which can consist of springs.
  • the urging means for each arm shown in figure 3 consists of a pneumatic actuator 34 or 35 consisting of a piston moving in a cylinder between extreme abutment positions and integral with a piston rod 36, 37 projecting externally.
  • each actuator pivots at one end of its cylindrical body, for example at 35a for actuator 35, on the corresponding sliding carrier (here sliding carrier 20a) which supports it while its piston rod 36 or 37 pivots by means of a forked arm and a pivot pin (at 37a on an extension 38 of arm 30 for actuator 35).
  • the piston and the piston rod are only able to have a limited stroke when the piston is at the bottom of the cylinder of the actuator whereby, as soon as the first and/second roll(s) cease to be in contact with their corresponding supporting roll (the roll 5 in the process of being wound or lay-on roll 25) it comes to a stop position without contact, being maintained by its piston.
  • a second train of rolls 24a providing an S-shaped path for film transfer and spreading before and after slitting, is provided ahead of the dual tracking lay-on roll train and consists of three rolls which, in the winding position shown in figure 1, lay substantially one on top of the other and mutually spaced from each other.
  • the length of the span of web between each of these rolls has been found to give the best results when this length is less than one-quarter of the width of the film, and is preferably one-eighth of this width.
  • the roll train consists of a third roll 39 providing transfer to the second roll 26 and having a smooth surface, for example in black anodized aluminum, for ensuring good adherence to the strip of film 2.
  • This third roll 39 is mounted idly on two end bearings each one of which is carried by a respective carriage such as a sliding carrier 21a and 21b sliding in a guiding surface such as linear guides 21.
  • the strip of film 2 passes over a portion of the surface of this third cylinder 39 in the same direction as over the second cylinder 26.
  • the third roll 39 is preceded, with respect to the direction of advance of film 2, by a fourth roll 40 the function of which is to ensure film spreading and transfer following trim slitting of the film.
  • This fourth roll 40 is also employed for measurement of the film tension, the bearings thereof being mounted at each side in suitable tension measuring cells, such as a load cell, in order to provide a signal to a tension control module.
  • the roll 40 is mounted idly in the said bearings each one of which is fitted onto a respective sliding carrier 22a and 22b which slides in linear guides 22.
  • the strip of film 2 passes over this fourth roll 40 in the opposite direction to that of the third and second rolls 39 and 26, and in the same direction as over the first roll 25.
  • the fourth roll 40 is preceded by a fifth roll 41 the function of which is to spread the film and stabilize it prior to trim slitting.
  • This fifth roll 41 is mounted idly on two end bearings each one of which is housed by the respective sliding carrier 23a and 23b moving in linear guides 23.
  • the strip of film 2 is wrapped around this fifth roll 41 in the same direction as over rolls 26 and 39 after leaving a feed roll 41a of larger diameter than the five rolls for film feeding and applying strip 2 before its winding onto roll of film 5.
  • the two sliding carriers of each one of rolls 39, 40, 41 of this second S-shaped roll train can move horizontally in parallel linear guides with synchronized movements, just like those of the two dual tracking rolls 25 and 26 of the first roll train.
  • the synchronization means for the two sliding carriers of a given roll consist, as already described for roll 25, of a synchronizing shaft which links (see synchronizing shafts 42, 43, 44 corresponding to rolls 39, 40 and 41 respectively) two gearboxes each mounted on one of the vertical plates 17 or 18, the gearboxes being linked by means of a rotating lead screw to the corresponding sliding carriers.
  • gearboxes 42a, 43a and 44a are shown mounted on vertical plate 17 and, respectively, correspond to synchronizing shafts 42, 43 and 44.

  • sleeves 45, 46, 47 and 48 are illustrated these being respectively provided on synchronizing shafts 31, 42, 43, 44.
  • Such a sleeve can be rotated together with one single portion of a synchronizing shaft and then once again locked with respect to the other portion of the shaft in order to enable one of the roll sliding carriers to be shifted with respect to the other sliding carrier, and then, after the sleeve has been locked onto the synchronizing shaft, to ensure synchronized movement of the two sliding carriers of a given roll.
  • sliding carrier 22a which incorporates one of the bearings of the fourth roll 40 faces the turret 3 carrying the wound rolls 5 rather than being directed away therefrom.
  • This reverse arrangement of sliding carrier 22a comes about due to the fact that sliding carrier 22a only moves by small amounts, mainly for adjustment purposes, unlike the other sliding carriers, and also as a result of the fact that it is necessary to house a hollow beam 49 of relatively large diameter, arranged transversely between vertical plates 17 and 18, behind the fourth roll 40. The purpose of this hollow beam 49 is discussed in detail below.
  • movement of the roll sliding carriers can be achieved by the use of stepping electric motors or dual-speed pneumatic motors coupled to the abovesaid gearboxes, in which, after movement of a roll, the air feed is interrupted and the sliding carriers are maintained in place by a brake mounted on the pneumatic motor or by an irreversible transmission system.
  • the hollow beam 49 supports one or several knifes or cutting elements 50, these being employed to slit the film 2, and are illustrated in figures 5 and 6 in rear and cross-sectional views on differing scales.
  • the hollow beam 49 links the two vertical plates 17, and 18, and carries, for example, two movable cutting carriages 51 and 52 which move by rolling on rollers 53 at the upper portion of beam 49 through rotation of a displacing and adjusting screw 54 which is parallel to the beam 49 and can consist of two coupled halves, one of which is left-threaded and the other right threaded.
  • This screw 54 can be rotated manually by turning an adjustment handle 55 which acts mechanically on the screw 54 through a gearbox 56.
  • each of the cutting carriages 51 or 52 can be moved, through a desynchronization sleeve 57, independently of the other for adjustment purposes, the corresponding knives normally being set to remove a trim or offcut at the two sides of the advancing web.
  • this shows the cutting carriage 52 carrying an upper sliding guide 58 on which a knife sliding carrier 60 moves transverse to the longitudinal axis of beam 49 by means of moving means such as a handle 59 in order to bring the cutting edge 61 of the knife 50 into contact with the film 2 which is tensioned between the fourth cylinder 40 and the fifth cylinder 41.
  • the knife sliding carrier is advanced or retracted by a short-stroke pneumatic table for the purpose of entering and withdrawing the knife 50 from the film 2.
  • the knife holder can be retracted from the rear of the apparatus well away from the film winding mechanisms, allowing it to be replaced without disturbing the winding setup.
  • Each knife holder 51 or 52 carries, via uprights 62 and 63 which surround beam section 49, a tube 64 for collecting an offcut strip 65 of film 2 (this can also be seen in figures 2 and 3).
  • the offcut or trim strip 65 is formed immediately downstream of knife 50 and passes over the fourth roller 40 in order to follow a curved path into the mouth 66 of a trim collecting tube 64, the inlet mouth opening below the fourth cylinder 40.
  • the trim collection tube 64 is normally subject to pneumatic suction but, in order to more readily draw off the strip of trim 65, the collection tube 64 is associated with a cutting knife 67 operating in the longitudinal direction which cuts the leading end of the offcut strip, enabling it to be readily introduced into tube 64 from whence it is readily drawn off and carried to a storage and recycling circuit after passing through a shredder fan or chopper common to all the trim collection tubes and which is not shown in the drawings.
  • adjustable stops stops 68 and 69 on linear guide 20, stops 70, 71 and 72 on the respective linear guides 21, 22, 23
  • these are designed to cooperate with a contact of an electrical and/or electronic switch means for stopping the drive motors which determine the movement of the two sliding carriers for each roll.
  • the transmission mechanisms 73 and 74 for driving shafts 43 and 44 for linking and simultaneously driving respective pairs of sliding carriers 22a, 22b and 23a, 23b can be seen.
  • the drive motors (not shown) for such mechanisms are for example flanged onto the gearboxes such as 43a and 44a in the example shown.
  • Figure 3 also shows a switch means 75 mounted on sliding carrier 23a which cooperates with stop 72 to bring to a halt the motor that drives the sliding carriers 23a and 23b providing the horizontal movement of the fifth roller 41.
  • figure 1 shows the apparatus in the production, in other words in the winding position
  • figure 4 shows the apparatus in the position where winding is about to start
  • figures 7 and 8 show the same apparatus respectively in a position where automatic changeover to winding another roll is occurring
  • the apparatus at automatic restarting of winding on a new core
  • sliding carriers 19a and 19b of the first roll 25 are moved by their respective drive motors to a retracted position in which the first roll, lay-on roll 25, is no longer in contact with the second roll, tracking roll 26, and with the outer surface of the core 6 of a roll to be wound, the arm 11 of the turret having rotated with respect to the position shown in figure 1.
  • a wide passage 76 has thus been opened up between the first roll 25 and the second roll 26 the sliding carriers 20a and 20b of which have not moved.
  • the piston of actuator 35 has now reached its stop position and rotation of the pivoting arms 29 and 30 has ceased in order to immobilize the second roll 26 in the position shown in figure 4.
  • the sliding carriers 21a and 21b and 23a and 23b of the respective third and fifth rolls 39 and 41 are advanced by their drive motors in order to adopt the position shown in figure 4 and to provide a clear passage 76 extending to the top of the apparatus.
  • a rigid film guide 78 which is movable in the vertical direction as illustrated in figure 4, and which is normally retracted during production, is then lowered to the position illustrated in figure 4 at which its discharge end is close to the rear outer surface of a previously mounted core 6 on arm 11.
  • the passage 76 provided by retraction of roll 25 and advance of rolls 39 and 41 allows the guide or thread-up tube 78 to pass without impediment. Closeness of tube 78 to the core 6, or to a partially-wound film surface, is preferably detected by proximity switch means which halt its downward movement. Thread-up tube 78 can thus approach the core very closely. The apparatus is now in a position at which actual thread-up can start.
  • the leader 77 of film 2 is blown through the thread-up tube 78 by a blowing tube 79 and the leader 77 is caught by the core 6 which can be electrostatically charged if necessary.
  • Other manners of attracting the leader to the core may be used such as introduction of fine droplets 77a of a liquid such as water in an air stream by means situated close to the core which are not illustrated, leading to the production of fine droplets on the surface of the film 2 which acts as a sort of adhesive between the core 6 and the film 2 or between two superposed layers of film 2.
  • the rigid film guide or thread-up tube 78 is retracted and the film is layed onto the large diameter feed roll 41a, and the third and fifth rolls, 39 and 41 respectively, are retracted to their far rear positions by operating their respective motors while the first roll 25 is advanced to its forward position to adopt the positions for normal production running illustrated in figure 1 or rather in figure 8 because only the starting layer of film, and not a plurality of layers, has been wound onto core 6, and the pivoting arms 27 to 30 are in the lower position, as shown in figure 8. If the film is to be slit or edge trimmed, the slitting knifes 50 are advanced, after winding of the film 2 onto the core 6 has started, to the position illustrated in figure 6.
  • lay-on rolls 25 and 26 are then advanced to the position shown in figure 8 in order to apply the film 2 firmly against the core 6.
  • An enveloper roll 16a carried by arms 16, the side end of which can be seen at the free end 81 of arms 16, is advanced by the arcuate shaped arms 16 to the position illustrated in figure 8 by rotation of a cam-shaped drive member 80 and suitable guiding of its movement by means which are not illustrated.
  • the film 2 is now applied to the empty core 6 over about 300° of its surface and adheres firmly to the surface of core 6.
  • a transverse knife 82 provided at the end 81 of arms 16 makes a transverse cut through the strip of film 2 and the trailing end of the wound roll 5 can now be wound, for example manually, onto this roll 5 which will be removed while winding is continuing on new core 6.
  • the enveloping device 16 is then retracted by rotation of drive member 80 and roll production continues on the new core 6.
