Definitions

  • Webs of fibres are more commonly removed from the doifer roller of a carding machine by means of a. hycomb and then passed between a pair of co-acting rollers which are ofiten employed for ironing the fibres and/or crushing seeds or other impurities.
  • a. hycomb When first starting the web across the gap between the doffer roller and coac-ting rollers it is common practice for an operator to feed the web in by hand to the nip of the rollers. As it is considered that this can be a danger to the operator because his fingers may be caught, it is desirable that some guard and/ or guide means be furnished to prevent injury to an operator and it is the main object of the present invention to solve this problem.
  • co-acting rollers as used generally hereafter is intended to include rollers to one or both of which positive pressure is applied, or where one roller of a pair rests upon the other roller, or where a roller is set to be in rolling contact with or spaced from the other roller.
  • apparatus for guiding and supporting textile webs between a doffer roller and a pair of co-acting rollens including a web supporting bridge plate mounted between the dotfer roller and the co-aeting rollers for an uncondensed web to pass thereover, said plate having its rear edge so positioned relative the pair of co-acting rollers as to facilitate the initial feeding in of the web between the rollers and to prevent a persons hand being inadvertently drawn into the nip of the rollers.
  • the bridge plate may have its rear edge located in a slightly higher plane than the contact line of the co-acting rollers and substantially closely adjacent the periphery of the upper roller without hindering the movement of a web.
  • the bridge plate may have its front part curved or inclined downwardly and adapted so that when positioned there will be a gap between the plate front edge and the doifer roller.
  • the bridge plate may be mounted inclined slightly downwardly towards its rear edge and mounted adjustably at least for initial setting. At least part of the bridge plate or an associated part may be displaceable.
  • FIG. 1 is a diagrammatic side view illustrating one form of bridge plate mounted in relation to a dofier roller and a pair of cosacting rollens;
  • FIG. 2 is a side elevation of a practical form of such a bridge plate
  • FIG. 3 is a part plan View of FIG. 2;
  • FIG. 4 is a diagrammatic side view of a hinged bridge plate with means for moving the plate when supporting a web;
  • FIG. 5 is a diagrammatic side view showing a two-part bridge plate
  • FIG. 6 is a side elevation of another type of two-part bridge plate
  • FIG. 7 is a part plan view of PEG. 6 on line AA.
  • FIG. 8 is a diagrammatic side view of a bridge plate hinged about one end for displacement purposes.
  • a bridge 3,ll3,348 Patented Dec. 10, 1963 plate 1 is formed of a Width to suit a carding doffer roller 2 and set of associated pressure rollers 3, 4 and of a length to suit the gap between such dofier roller and pressure rollers.
  • the rear edge 5 of the plate 1 is carried by mounting means and is shown bent around a cross rod 6 (or other round section member) which has its ends projecting for mounting in side brackets 7. These brackets are mounted on the framework 8 of the pressure roller machine assembly and disposed wholly below the bridge plate 1.
  • the forward part 9 of the bridge plate is preferably curved, or inclined, downwardly for a given distance and when the plate is positioned the front edge of this part is spaced a pre-determined distance from the periphery of the dozier roller 2.
  • the rear edge 5 ot the plate is preferably, but not necessarily, located in a plane slightly above the plane of the nip of the pressure rollers 3, 4 and with such rear edge substantially close to the periphery of the upper roller 3 which will be rotating so that a Web delivered from the bridge plate will be carried downwardly a short distance to the nip of the rollers.
  • the bridge plate is inclined slightly downwardly from front to rear to facilitate the feeding of the web thereover and moreover the surface of the plate is preferably polished or finished with a substantially frictionless surface. If so desired, the plate may be in effect hingeable about its rear edge, e.g. the axis of the rod 6, and furnished with adjusta'ble stay means.
  • an adjusting screw it ⁇ with a lock nut 11 is passed up through the part 12 of the bracket 7 which lies beneath the plate :1.
  • a screw 10 is provided at each side of the plate. The adjusting screws will at least allow the bridge plate to be initially set in a desired plane, i.e. either horizontal or with a desired inclination.
  • the numeral 14 is a blower nozzle.
  • a bridge plate constructed and located as described facilitates the initial guiding and supporting of webs over the gap between dofiing and pressure rollers as it has been found that at the very most only a slight hand movement on the part of an operator is required to start the web between the pressure rollers.
  • the provision of a curved or inclined front part to the plate and a gap between it and the dofier roller the accumulation of trash and fly" is eliminated or at least minimised and should any trash" be accumulated, it tends to fall away between the bridge plate and dotier roller.
  • the positioning of the rear edge of the bridge plate is such that it acts as a guard against the possibility of an operator being injured by having a hand drawn into the nip of the pressure rollers.
  • side cheek plates r13 project above the surface of the bridge plate and these are flared outwardly towards the front edge so as to constrain any tendency of the web to rub against protruding frame parts.
  • the cheek plates may be integral with, joined to, or associated with the bridge plate.
  • cheek plates may be independently mounted or carried by the bridge plate or its mounting.
  • one or more air jets Ki. 1 may be furnished to blow the fibre web towards the pressure rollers or a rotary or other device be furnished, say in the fashion of a skeleton paddle wheel 15 (FIG. 2).
  • the bridge plate may be mounted to have a limited hinging movement about its rear edge 5 so that the plate can be fiapped up and down to assist the initial travel of a Web thereover to the pressure rollers.
  • one or more cams 16 may be mounted beneath the plate 1 to support it (the cam shaft 17 may be adjustably 3 mounted for setting the plate) and when rotated cause the plate to rise and fall.
  • FIG. 5 A further modified constnuction is shown in FIG. 5 wherein the bridge plate is in two parts 1 and 1a associated at 18.
  • the part 1a may be hinged, or located adjacent, to and be supported in its operative position in any convenient manner.
  • a pair of levers 19 may be hinged to the plate and bracket part 12 respectively and have a lockable common pivot 20 which will allow adjustment of the plate 1a and when released let the said plate swing down out of the Way of a web.
  • This type of construction is illustrated in a modified form in FIGS. 6 and 7.
  • a short plate 1 with long cheek plates 13 is mounted as previously described for FIGS. 2 and 3 and an extension plate 1b is hingeably attached thereto.
  • Said plate 112 extends only part way across the width of plate 1 (it may extend the Whole width) and is provided with downturned side flanges 21 for mounting it on the pivot pins 22 carried by one check plate 13 (both when a full width plate 1b is used) and a log 23.
  • the plate 11b is supported by a lever 24 pivotal ly anchored thereto and having a slot 25 for receiving a mounting pin 26.
  • the slot end has a lever retaining notch 27 and the lever end forms a gripping handle 28.
  • a complete bridge plate 1 may be mounted to be moveable down from a web supporting position as indicated in FIG. 8. By curving the plate at 5a to a radius struck from the pivot 6 it will still give support to a Web adjacent the nip of the rollers 3, 4 and form a guard for the operator.
  • a bridge plate or an associated part is mounted to be capable of swinging down, should there be any tendency for trash to accumulate at the front end of the plate it can be disposed of by dropping the plate or part.
  • the plate or part can be left down or moved back to a web supporting position.
  • the bridge plate has its rear edge curved in a substantially small radius about a pivotal axis, and screw means for adjusting the plate about said axis for setting it in its operative position.
  • the bridge plate has upstanding side cheek plates, said cheek plates extending beyond the front edge of the bridge plate and flaring outwardly to and partly on each side of the dofier roller so as to facilitate side guiding of the web from the doifer roller to and over the bridge plate.
