Definitions

  • the present invention relate to a m chine for the manufacture of shape-retaining cotton-wool pressings from a roll, in particular for the production of pads.
  • Various machines of the type are known but the majority displays the disadvantage that their output is low.
  • the press dies carrying a control roller and the swivelling clamping jaws between the tool holder plate and a carrier ring connected, by way of example, by means of the pivot pin are movably arranged.
  • the pivot pins of the clamping jaws are provided with a lever arm carrying a guide roller for a cam which is arranged below the tool holder plate on the machine housing. This provides a very simple and reliable control means for the clamping jaws.
  • the control roller and its associated cam for the press dies are conical so that an alteration of the press die stroke will be caused by an axial displacement of the cam face.
  • the press dies are returned by a separate return roller controlled by a cam ring.
  • Fig. l is a fragmentary vertical section of the machine
  • Fig. 2 is a horizontal section taken along line ll'II of Fig. 1,
  • Fig. 3 is a vertical section along line 111-411 in Fig. 1, and
  • Fig. 4 is a section taken along line lVlV in Fig. 1.
  • the machine housing 2 Arranged on the baseplate 1 is the machine housing 2 which is at its centre equipped with a guide housing 3 for the driving shaft 4 held in ball bearings 5 and 6.
  • the shaft 4 has its lower end provided with a gear 7 which is rotated, by way of example, by a chain drive (not shown).
  • the other end of the driving shaft 4 carries a head member 8 holding the tool holder plate 9.
  • the carrier ring 10 Below this tool holder plate is the carrier ring 10 which is carried, by way of example, by the pivot pins 11 of the clamping jaws 12.
  • the pivot pins 11 of the clamping jaws carry a lever arm 13 (Fig. 3) below the carrier ring 10, which lever is provided with a guide roller 14 for the cam 15.
  • the cam 15 is seated and fixed in a horizontal portion 42 of the housing 2 as can be best seen in Fig. 1.
  • the guide rollers 14 glide in the cam 15 and thereby control the clamping jaws.
  • a ring 16 Arranged in the interior of the machine is a ring 16 which is designed to support a cam. Above the ring is provided a cam guide 17 for a control roller 18 arranged at the end of a press die 19. A portion of the surface of cam 17 engages roller 18 for displacing the dies 19 outifi iiijfil Patented June 14], 1960 2 V wardly, while at other times the cam provides a guide for maintaining the dies 19 in desired position.
  • a return cam 20 is provided which acts on a roller 21 so that the press die is forced outward by the cam 17 and retracted inward by the roller 21,.
  • the rolls 30 to be pressed are forced into themachine at one station while the clamping jaws 12 are open; on further rotation, the clamping jaws 12 first close as appears from Fig. 2. Subsequently the press die 19 is fo ced outwards so that the roll is completely compressed into a circular pressing.
  • the shape desired is obtained by the design of the clamping jaws and the front end of the press die.
  • the pressings then remain in this compressed position during a further rotation so that they will retain their shape after being ejected later.
  • This ejection as shown in Fig. 2 as well, is effected by a further outward advance of the press die 19, the clamping jaws 12 being then open again.
  • the cam disc 17 and the control roller 18 are conical.
  • the cam 17 can be adjusted for height via a bush 31.
  • a manually actuated control shaft 22 is arranged which rotates a rim having a trapezoidal thread 25 via bevel gears 23 and 24 so that the bush 31 is adjusted for height.
  • the press dies 19 can, by way of example, be held by guides 19:: (Fig. 4) which are screwed to the underside of the tool holder plate 9.
  • the height of these press dies and accordingly the space between the tool holder plate 9 and the carrier ring 10 substantially corresponds to the length of the pressing to be produced.
  • the rolls 38 inserted into the machine either by hand or automatically by means of a turntable, forming no part of the present invention, which is located adjacent to carrier ring 10 are heated in the known manner in order to improve their shape retention.
  • the machine housing 2 and the cover 29 arranged above the tool holder plate 9 are equipped with insulating layers 26 and 27.
  • the pressed rolls may, of course, be removed by hand or may gently fall down a chute of conventional construction and forming no part of the present invention. Alternatively, a pickup table may be employed.
  • a machine for manufacturing a tampon-shaped pad and like article comprising a rotatable drive shaft, a holder operatively connected with said shaft for rotation therewith, a carrier spaced from said holder and operatively connected for rotation with the latter, pairs of forming jaws shaped for engagement with each other at respective ends thereof, pairs of spaced pivot pins extending from said holder to said carrier and arranged for receiving respective forming jaws, so that said forming jaws may be spaced apart from each other and brought into engagement with each other, press die means disposed for reciprocable movement within the space between adjacent pivot pins and beyond the respective adjacent pivot pins and said forming jaws, first means for controlling said reciprocable movement of said press die means and for displacing the latter in predetermined sequence to each other, and second means for controlling the movement of said forming jaws from a position, in which said forming jaws engage each other thereby providing space therebetween for receiving said article forwardly of said press die means for compressing said article against said engaged forming jaws, to a
