Definitions

  • the invention as a subject, has a curved extension roller for textile fabric, paper and similar material.
  • the invention refers to the supports on the extremity of the curved rollers provided with means for the drag in rotation and for the continuous regulation of the inclination of same rollers.
  • Each one of the two supports on the extremity of the curved rollers accomplishes a task; one of them provides the means for the motorized drag in rotation of the roller, whereas the other provides means, also motorized or by manual control, for the continuous regulation of the inclination of the roller during it's rotation.
  • Document BE-A-768516 discloses a curved extention roller for textile fabric, paper and similar material with its extremities fitted rotatably in respective first and second supports in a frame and rotatably driven by a first motor, means being provided for the continuous regulation of the inclination of the roller, the roller comprising a central shaft around which is fitted a revolving external covering which is rotatably driven relative to the shaft by the first motor, the shaft extending beyond the covering at one extremity of the roller and being pivotally connected to one end of a stub shaft rotatably mounted in the first support, the other end of the roller being connected with the first motor through a cardan joint within the second support, a second motor being connected to the other end of the stub shaft in the first support for rotation of the central shaft to provide regulation of the inclination of the roller.
  • connection between the covering and the cardan joint is realized by means of gear wheels and cog-belts.
  • the aim of this invention is to propose supports provided with means for the regulation of the inclination of the rollers of more simple realization which does not require particular processing of precision and therefore are not subject to wear or damage, nor require periodical maintenance.
  • the invention proposes the realization of a curved extension roller for textile fabric, paper and similar material as described on BE-A-768516 and further characterized in that the covering extends beyond the central shaft at the other extremity of the roller and is connected to the cardan joint by means of a pin rotatably mounted in the second support.
  • This curved roller 10 is constituted by a central shaft 11 on which is fitted a revolving the covering 12, by means of ball-bearings 13.
  • the central shaft 11 extends with an extremity 14 of the covering 12 and pivots in 15 to a hub 16 which is fitted revolving in a support 17, by means of ball bearings 18.
  • the other extremity of the shaft 11 terminates inside the covering 12, which is screwed into a bush 19, of which a pin 20 fitted revolving in a bush 21, joint to the framework 22 which carries this group and to a box support 23 on the outside of the framework 22.
  • the shaft 24, extremely of support 23, carries a keyed pulley 27.
  • a cog belt 28 connects the pulley 27' of the intermedium roller with the pulley 27 of an external roller
  • a second belt 29 connects the pulley 27' ofthe intermedium roller with the pulley 27" of the other external roller.
  • the latter receives the revolving drive, which he transmits to the other rollers 10, from a motor 30 through a belt 31. It is obvious that this system of transmission, illustrated in fig.
  • the hub 16 which is fitted revolving in support 17, joint to the framework 22, carries keyed-on, on his extremity 32, a gear-wheel 33.
  • a gear-wheel 33 As one can see in fig. 3, always considering that the group consists of three rollers, as in fig. 2, and not observing now the transmission means of the revolving drive of fig. 2 of side A of the framework 22, but rather the means of regulation of the inclination put on side B of the framework 22, one can observe as every hub 16 of each roller carries keyed-on an identical gear wheel 33 and all of them are engaged with an endless screw 34 which is driven in rotation by a motor 35, by means of opportune gears (not illustrated).
  • roller 10 is interupted for simplicity, but one can observe that he has a quite strong curve. Roller 10 has to revolve and at the same time has to be inclinable in order to vary his angle-shot to the fabric, or paper or other material which passes through the various rollers of the group.
  • the motor and transmission devices of Fig. 2 and of the left support in Fig. 1, are destinated to put in rotation the roller 10.
  • the motor 30 puts in rotation the pulley 27, 27' and 27", which by means of the cardan joint 26 turn the pin 20 and with the latter the covering 12 of the roller 10.
  • the cardanic joint 26 has the very advantageous task, according to the invention, to transmit the rotative movement at any angle of inclination of roller 10 in respect to the horizontal passer-by axes of shaft 25.
  • the motor and transmission devices of fig. 3 as well as the right support in fig. 1, have the task to allow continuously the inclination of roller 10 during it's rotation as previously described.
  • the motor 35 puts into rotation the screw 34, which at it's turn, makes rotate simultaneously the cog-wheels 33 of each roller, and these make rotate the respective hubs 16 in which are pivoted at 15 the pins 11 of each roller.
  • the covering rotates at it's exterior, the curved shaft 11 can be inclined at any angle and therefore one realizes such combination of motion in rotative sense (external) and angolar sense (total) typical - for such curved extension rollers.
