  • the position of the fabric cutting device 52 on chain 50 as well as the pitch of nut 56 and of the threaded part of shaft 55 are such that each time the device 52 carries out a transversal cut of the fabric 34 in the direction of the arrow (FIG. 7), at the end of the path the axial displacement of nut 56 due to rotation of shaft 55 lifts up lever 62 and the lock 66 by an amount sufficient to unlock the drawer 25.
  • the fabric cutting device 52 (FIGS. 5 and a) comprises a driving support 70 connected to the control chain 50 and slidably mounted parallel to the winding shaft 20 on a rack 7I.
  • the cutting member proper is formed by a sharp edged disc 72 rotating with a pinion 73 meshing with the rack 7I, the fabric 34 being guided towards the disc 72 by an inclined plane 741 provided on the support 7th and carrying out the function of a fixed knife.
  • FIGS. 5 to 7 also show a variation of the means for moving the drawer 25 and the fabric cutting device 52, the chain II which drives the drawer 25 and the chain 50 which drives the fabric cutting device 52 being respectively driven by reversible electric motors 75, 76.
  • the supply of the driving motor '75 of drawer 75 of drawer 25 is controlled from the cutting device 52 and, to allow the removal of a roll of knitted fabric, avoiding any risk of error of manipulation, the current supply to the two motors 75 and 76 can be effected only when the winding mechanism is oriented to allow the drawer 25 to be displaced outwards of the knitting machine, as shown in FIG. 2. In this position the drawer 25 can slide between two legs 2 of the fixed frame, contact means being provided on the frame to cut off the current supply of the main driving motor(s) of the knitting machine when auxiliary motors 75 and 76 are supplied with current.
  • FIGS. I2 and I3 A preferred embodiment containing the abovementioned features is shown in FIGS. I2 and I3.
  • FIG. I2 illustrates schematically the main elements shown in FIG. 2; in this figure the same reference characters are used as in FIG. 2; for the same components.
  • the main driving motor IIII of the knitting machine is supported by one of the three legs 2 at the base of which are disposed two switches MP2 and IIIEI respectively provided for controlling the slowing of the speed of the frame, either by restricting the speed of motor IIII, or by switching a low speed auxiliary motor (not shown), and to stop the mtor(s) thus stopping the knitting machine.
  • the successive actuating of the two switches W2 and I03 is effected by means of a cam I614 disposed on the rotating toothed crown I which supports the mechanism, so that drawer 25 can be displaced between the other two legs 2 of the frame.
  • the circuit of switches I02, I03 is controlled by a third switch I05 which is also fixed to a leg 2 of the frame and can be controlled by the user.

  • microswitches I09, IIII are fixed on the rotating crown and are disposed on the path of cams III, I112 fixed to the cheeks 27, 29. Said microswitches corre spond respectively to the start and the end of the displacement of the drawer 25, whereas two other microswitches II3, IM are fixed inside the side plates 6, 7 and determine when contacting the driving support member 70, the end and the start of the stroke of the cutting device 52.
  • the casing I07 comprises three relays R R R which can be actuated by two control buttons II5, I16 corresponding respectively to the pulling out of the drawer 25 and its return to the initial position. Electrical connections between motors 75, 7th to these various elements are shown in FIG. 113 where the knitting machine is in action, before the removal of the roll of knitted fabric.
  • the user To control the automatic removal of a roll of knitted fabric out of the frame, the user first actuates switches IIIZ, I03, and cam MM stops the knitting machine as it passes, and the winding mechanism is in the position shown in FIG. I2. The user connects plug IIIb to the casing IIW, said plug receiving current only when the mechanism is in this position.
  • FIG. I3 shows that in addition to the-four pins provided for the supply of the current to motors 75, 76, two other pins are provided respectively for supplying the low voltage current of the relays R R R through the microswitches controlled by buttons I115, I116. Such two other pins are provided for closing the excitation circuit of a relay R disposed in the supply circuit of the main motor IIII, so as to prevent any current to the latter when switch III 6 is connected to the casing.
  • Relay R is a part of the general current supply circuit of the knitting machine (not shown).
  • the relay R By pushing button IIS, the relay R, is excited, the contacts r are released and said relay R supply current to the motor 76 of the cutting device 52.
  • the latter when it moves transversally, connects microswitches II l, II3 respectively at the start and the end of its displacement.
  • Switching on of the microswitch I13 excites relay R which controls an assembly of contacts r for controlling the current of motors '75, 76, and the motor 75, which in turn receives a current, drives the drawer 25, while the roll of knitted fabric slides axially on the winding shaft 2%, as shown in FiG. I2.
  • microswitches I09, III respectively for the start and the end of the displacement of the drawer 25, is modified during the latter's displacement by the actionof corresponding cams III, III.
  • Microswitch IIII releases relays R R which act upon contacts r r associated therewith. The cut off of current supply to motor follows, and consequently the drawer 25 is stopped, whereas the assembly of contacts r return to their initial position.
  • FIGS. 8 and 9 show the means for controlling wind ing of the knitted fabric.
  • a flap 77 extending across the width of the wound fabric 34 is fixed on a pivotal shaft 78 supported at its ends by the plates 6 and 7 of the main support 5.
  • a traction spring 79 held, on the one hand, on an end of a two armed lever 80 fixed on an extension of shaft '78 and, on the other hand, connected to a lever 811 of the friction device 21 tends to constantly apply the lower part of flap 77 towards the winding shaft 20.
  • the grippers 82 are also inclined in relation to the longitudinal direction of shaft 20 in a manner such that their pointed ends 83 are oriented in the direction of movement of the drawer during removal, thus enabling the roll of fabric to slide over shaft 20 at the moment of removal.
  • This result could alternatively be obtained by pivotally mounting the grippers 82 on the rotary shaft 20 in a manner such that these grippers can pivot in the direction of axial movement of a roll 35 of fabric when a push is exerted thereon by the roll 35 of fabric during removal.
  • the second end of two armed lever 8(1) is also adapted to come into contact with a shoulder 85 of the nut 56 controlling unlocking of the drawer 25. As indicated in broken lines in the left of FIG. 9, this arrangement enables the flap 77 to be moved out of the path of cheek 29 of drawer 25 as soon as the fabric 34 has been cut by the device 52.
  • the friction device 21 controlling rotation of the shaft 20 from the fabric draw off rollers is shown in detail in FIG. 8.
  • the wheel 22 driven by chain 23 is fixed on driving plate 86 freely turning on the end of shaft 20 by means of a ball bearing, whilst an adjustable driven assembly 88 is keyed on the shaft 20. Adjustment thereof takes place, via a ball joint 89, from an axial movement of a rotating sleeve 90 centred on a shouldered part of a bearing 91 fixed on the vertical plate 6 and supporting the end of shaft 20 by means of a ball bearing 92.
  • the facing faces 93, 94 of rotating sleeve 90 and bearing 91 include protruding parts 95, 96 respectively, as shown on the partial plan view of FIG. 10, and which have inclined complementary surfaces 97, 98.
  • Lever 81 connected, as previously described, by a spring '79 to the end of pivoting lever 80, is fixed on a shoulder of sleeve 90.
  • the tension of spring 79 thus increases and as a result the two inclined surfaces 97, 98 slide over one another, which causes a slight axial movement of sleeve 90 which, via the ball joint 89, increases the pressure exerted by the assembly 88 on the driving plate 86.
  • This arrangement insures a constant tension on the fabric as it is wound and while the inertia of the fabric roll 35 increases due to an increase in diameter thereof.
  • the described mechanism notably facilitates the work of the operator who is no longer required to manually act on the knitted fabric, either to ensure its winding or its removal from the knitting machine frame.
  • said support comprises at least one movable part forming bearing means for supporting one of the ends of said rotary shaft with said bearing means being releasably mounted with respect to one shaft end for freeing said end when said movable part is displaced;
  • said mechanism further comprises a fabric cutting device
  • a movable pushing member for exerting an axial push on a roll of knitted fabric on said rotary shaft towards said bearing means
  • a mobile fabric guide cooperating with said rotary shaft on which the knitted fabric is wound.
  • a mechanism according to claim 2 further comprising means for moving said cutting device parallel to said axis'of said rotary shaft, a stop, locking means cooperating with said stop for locking said assembly on said support in a position in which said rotary shaft is held by its ends to allow the winding of knitted fabric thereon, and means controlled by said means for moving said cutting device for acting on said locking means to free said assembly after said cutting device has transversally cut the knitted fabric.
