Definitions

  • the present invention concerns a machine for continuously plating and embossing hides and the like, in the field of tanning.
  • a platen press In a first type of press, called a platen press, the hide, compensated by a felt, is placed between two opposing planes which, approaching each other, causes the said hide to be compressed.
  • a roller press In a second type of press, known as a roller press, the hide is passed between two opposing rollers with parallel axes which, approaching each other, causes the hide to be compressed as it runs between them, transported by a felt or a belt.
  • Both types of machine are more or less optimum for the specific type of skin being processed.
  • platen press is characterised by an optimum quality of the finished product, as it is possible to exert high pressures over a wide area, but it has the disadvantage of low productivity because the plates must be opened and closed at each successive compression action of the hide.
  • the roller press although it gives greater productivity as the hides advance continuously between the two processing rollers, has the disadvantage of only exerting pressure over a small area, that is to say along the tangent line of contact between the hide and the top and bottom processing rollers; this prevents the application of high pressures, which would be exerted over a limited area of the hide and damage it.
  • hides tanned with the new ecological system use products which can be diluted in water, and which require a reaction time to reticulate, ie to affix the plating and embossing action on the surface, significantly greater than the times required for hides tanned with chemical solvents, in a ratio of up to one to four, so that, even using a roller press, the processing cycle is significantly longer to obtain a final product of quality.
  • the aim of the present invention is to make a press for plating and embossing hides, tanned in the traditional mode or in the ecological water-based mode, which permits high productivity and better quality products to be obtained than is possible with the known types of machines.
  • the plating and embossing press is composed of a heated rotating cylinder, which acts as an operating roller having its external surface polished or engraved, on which the hide to be processed is wound through a wide angular aperture; the said hide is put under compression against said surface of the operating roller by the thrust actions exerted by an external belt, in turn would round the said roller with an equal angular aperture, said hide and said belt advancing at a rate equal to the peripheral velocity of said operating roller.
  • the external thrust belt preferably of the closed loop type, is capable of running on intermediate rollers and on a movable drive roller which gives the belt the necessary tension, which, apart from pressing the hide against the external machined surface of the operating roller, also rotates the said operating roller when it is mounted idle on the machine, in other words it is not rotated by its own special motor reducer.
  • said belt is shaped so as to act also as a plane of support and as a conveyor belt for the hide in the zone of insertion between the rotating cylinder and said thrust belt.
  • the continuos plating and embossing machine 1 consists of a rotating cylinder 2, which acts as an operating roller and is heated by means known per se , such as diathermic oil, steam, water or electrical resistance heating and which has its external surface polished or appropriately engraved.
  • a rotating cylinder 2 which acts as an operating roller and is heated by means known per se , such as diathermic oil, steam, water or electrical resistance heating and which has its external surface polished or appropriately engraved.
  • On said cylinder is wound, by an angular aperture preferably greater than 180°, a portion of a belt 3, which advances at a rate equal to the peripheral velocity of the said cylinder.
  • the hide 4 which is placed with the surface to be treated in contact with the machined surface of the said cylinder and advances at the same velocity as it.
  • the plating and embossing action of the hide 4 is performed as the said hide is held and pressed against the surface of the cylinder by the thrust action exerted by the external belt which operates in conditions of significant tension in the direction of arrow F (see Figure 3).
  • the belt 3, of the closed loop type, of felt or other material suitable for the purpose, is wound over a number of intermediate rollers 5, one of which 6' acts as a drive roller, and a second 6'', mounted on a bracket 7, is capable of sliding between guides 8, provided on the shoulders 9 of the machine, so as to control the tension of the said belt.
  • the value of the tension on the belt 3 is one of the decisive parameters for the success of the plating and embossing operation of the hide, therefore the micrometric displacement of the bracket 7 is performed by a motor reducer 10 controlled by a load cell 11.
  • the said belt 3 is always configured so as to present one of its flat portions 12 on which the hides 4' to be treated are placed, by the operator or by known means, so as to function, by its continuous advance, as a conveyor belt for the hide in the work area.
  • laminar device 13 which provides for the removal of the hide 4 processed by the surface of the cylinder 2, when the hide is inserted from the flat portion 12 and the said cylinder rotates anticlockwise (direction of the black arrow); alternatively the said device acts as a plane of insertion for the hide when the said cylinder rotates clockwise (direction of the clear arrow), depending on the type of hide or the feed system.
  • Another advantage derived from the use of the machine according to the invention is the possibility of continuously embossing "WET BLUE” or dyed leather with optimum results giving a degree of humidity up to 40%.
  • the machine In such operating conditions the machine is fitted with a belt or felt capable of absorbing part of the water expelled from the wet hide.
