Definitions

  • the present invention a machine for finishing skins and the like, according to the preamble of claim 1.
  • roller machines in which the skins are transported by a roller or by a rubber mat and pressed against an opposite, engraved roller, which deposits on the surface of the skin a uniform film of liquid, which has been previously distributed on the engraved roller itself by one or more doctor blade.
  • the engraved roller can rotate in "synchro”, that is to say in the direction concordant with the direction of advancement of the skin or in “reverse”, that is to say in direction reverse of said sense of skin.
  • the perfect success of the skin finishing operation depends on many factors, among which the predominant ones are regular entry of the skin into the constricted area, i.e. the area between the engraved roller and the roller or carpet underlying carrier, and a well-defined force for compressing the portion of skin which comes into contact, almost tangently, with the surface of said engraved roller.
  • all known solutions provide guide elements placed in the immediate vicinity of the constricted area and suitable for resulting in contact with the upper surface of the skin.
  • the object of the present invention is to provide a device to be applied to a "reverse" roller bumper machine which guarantees regular advancement of the skin in the tightened working area.
  • the converging profile of the guide member has a lower surface which comes into contact with the skin without exerting any type of pressure on the skin itself, while said surface will further delimit the introduction channel of the skin in the constricted area and is provided with means for reducing the contact area between this surface and this skin, like notches arranged with their axis parallel to the direction of advancement of the skin or with their axis diverging with respect to this steering, arranged symmetrically with respect to the median of the guide member himself.
  • said guide member is mounted on supports sliding so that, in case the anterior part of the skin lifts and, being driven by the engraved cylinder, it turns against the guide member, that said guide member, thanks to its sliding support, is pushed back, and that abnormal movement comes to excite a micro switch which immediately stops the operation of the machine and removes this body definitively from the constricted area, thus promoting the extraction of the skin.
  • the skins 1 are introduced into the zone tightened 2 working, defined by the engraved roller 3 and by the conveyor belt 4 placed below the roll, by means of devices known per se such as a pair opposite belts 5 and 6 which delimit a supply channel 7.
  • the engraved roller 3, fitted with the doctor blade 8, which contains the chemical finishing liquid 9, turns in “reverse” mode, according to arrow 10, that is to say in the opposite direction to the direction of advancement of the skins (arrow 11) and to the direction advancement (arrow 12) of the conveyor belt 4.
  • a guide 14 placed immediately upstream of said constricted zone, which member, provided with a converging profile or end 15, penetrates as much as possible into this zone and extends over the entire width, or transverse dimension, thereof.
  • the lower surface 16 of the converging profile 15 will be placed near the skin portion 17 placed immediately upstream of the constricted area.
  • notches or grooves 18 which reduce the contact area between said surface and the skin 17, as is can see it in Fig. 3.
  • the profile of the notches 18 can take different conformations, depending on the type of skins to be treated, with their ridges of a shape which goes from the rounded shape 19 to a flat shape 20.
  • the guide member 14 is slidably mounted, by means of the stirrups 21, on the bars 22 so that, when the skin 1, driven by the engraved roller 3, lifts and turns over (see detail of Fig. 6), said member is pushed back, going to request the microswitch 23 which stops the operation of the machine.
