Definitions

  • the process according to this invention is characterized in that it provides for arranging the sheets to be dryed, in succession, on a web of a pliable, liquid-pervious material, wrapping said web with the sheets superposedly placed thereon about a supporting axle, charging the thus formed roll in the interior of an autoclave and subjecting said roll to an axially flowing stream of dyeing liquor at high temperatures and under high pressures.
  • a carriage 10 In the interior of the cylindrical body 2, there are secured two longitudinally arranged rails 8, which support and guide, by the agency of idlers 9, a carriage 10: the latter is comprised of two header pieces 11, mutually connected by longitudinally running bars 12 (FIGURES 2-4).
  • Each of the two header pieces 11 of carriage 10 supports a corresponding end of a cylindrical member, or drum, 13, about which a roll 14 is wrapped, which is formed by sheets of the material to be dyed, 15, arranged in succession in end-to-end relationship on a gauze web 16 which acts like a spreader.
  • the autoclave 1 is equipped with a heating coil 50 to be fed with steam or another heating fluid under the control of a valve 51 , and a cooling coil 52 is likewise provided, which is fed with water or another coolant under the control of a valve 53 (FIGURES 1 and 2).
  • the dyeing step takes place, as a rule, as follows :
  • the gauze web 16 is gradually paid off of the roller 58, the supporting hub of which, 57, thus gradually approaches the delivery roller 60 and falls along the guide 59.
  • the gauze web 16 is wrapped together with the wood sheets about the drum 13 and the roll 14 is thus formed.
  • the roller 71 controls the gradual fall of the incline 70 so as to hold the web 16 always tangentially of the roll 14 in the point where the wrapping stage is started.
  • the roll thus prepared, completed with its foraminous discs 17 and headers 22, is placed on a carriage such as that shown at 10 in FIGURES 1 to 4: carriage 10, by means of another carriage, is then conveyed to the mouth of the cylindrical section 2 of the autoclave and is slipped thereinto and caused to roll over the guides 8.
  • carriage 10 by means of another carriage, is then conveyed to the mouth of the cylindrical section 2 of the autoclave and is slipped thereinto and caused to roll over the guides 8.
  • the end flanges 23 and 26 of the drum 13 and the ring 20 are brought to engage the fixed flanges 24 and 27 (appropriate gaskets being inserted therebetween), re - spectively, and the whole assembly is latched in the desired position by tightening the fly nut 31 onto the screw-threaded portion 32 of the stud 33 and thus against the dish 30.
  • an appropriate setting of the butterfly valves 40 and 41 provides an outlet back-pressure which originates a rise of the pressure of the liquid flowing through the roll 14 up to a high value such as for example, 5 bars.
  • the dyeing liquor is thus compelled to reach evenly and at a high temperature all the interstices of the wood and a satisfactory finishing is thus achieved.
