Definitions

  • non-heated drums are arranged above fixed heated troughs which also serve the purpose to urge the articles against said drums.
  • the surface of said troughs is permanently subjected to strong cooling by the damp articles, which practically means a serious reduction in the drying and ironing effect.
  • a further reduction in the efiiciency is due to the imperative provision of steam discharge openings.
  • drying and ironing calenders of low efficiency which have a single heated ironing drum of considerable diameter, said drum being provided with a plurality of guide rollers.
  • These calenders do not provide good results both with respect to the speed of operation and with respect to efliciency and ironing quality, so that many manufacturers have stopped production of machines having one ironing drum only.
  • the present invention provides an ironing machine for clothes, textile fabrics or the like, which comprises a motor group connected to a variable speed transmission by means of a belt; a reduction gear connected to said variable speed transmission and having a gear transmitting the movement originating from said motor group to a first chain in a desired transmission ratio; a tensioning means having a gear to hold said first chain under tension; a first heated ironing drum having secured thereto a gear; a second heated ironing drum having secured thereto a gear, said first chain connecting the gear of said first drum to the gear of said second drum, and said gears having different diameters so as to impart to the second drum a greater circumferential speed than to the first drum; a further gear secured to said gear of said second drum; a third heated ironing drum having secured thereto a gear, and a second chain connecting said further gear to said gear of said third drum, said further gear of of said second drum and said 3,487,566 Patented Jan. 6, 1970 gear of said third drum having different diameters so as to impart to impart to
  • the ironing machine of the 5 invention further comprises tensioning means having a gear to keep the second chain connecting said second drum to said third drum under tension; a further gear secured to said gear of said third drum; a third chain engaging said further gear of said third drum and three other gears, the first of said three other gears being carried by tensioning means, while the second one is secured to a roller arranged to drive a plurality of neighboring pretreated and reinforced asbestos aprons, and the third one has the function of keeping said third chain in permanent engagement with a plurality of teeth of said second gear; and a gear carried by the gear of the first drum and providing rotation of a fourth chain which travels round a plurality of further gears.
  • the ironing machine of the invention differs from all conventional machines in that a plurality of heated ironing drums is provided, which heated ironing drums preferably are arranged in horizontal parallel relationship, are driven at speeds increasing from drum to drum, and have identical diameters.
  • Associated with said heated ironing drums are a plurality of rollers, which provide a predetermined path for the articles. Over the majority of this path, the articles are in contact with the surfaces of the heated ironing drums which determine the degree of drying and ironing of the articles.
  • the machine proposed by the invention provides the possibility of keeping the diameters of the heated ironing drums small without affecting their efficiency, said possibility being due to the favorable structural and operational features of the machine.
  • the machine of the invention offers considerable advantages over the conventional machines having drums of considerably greater diameters.
  • Of particular advantage is the fact that by avoiding the provision of any 'fixed troughs, power consumption of the proposed machine will be considerably smaller.
  • a plurality of fiber glass belts may he provided which, from a transport roller to a guide roller, travel side by side along a path identical to that of the asbestos aprons, the articles being located between the asbestos aprons located on the outside and the fiber glass belts located on the inside throughout the path of said articles through said machine.

  • FIG. 4 is a schematic side elevational view, showing the heating circuit for the ironing drums.
  • the ironing machine proposed by the invention includes a motor group 1 which is connected to a variable speed transmission 2' by means of a belt 3, said transmission 2 on the other hand being connected to a reduction gear 2.
  • the reduction gear 2 has a gear 4 which transmits the movement originating from the motor group 1 to a first chain 5.
  • the chain 5 is held under tension by means of a gear 7 of tensioning means 6.
  • the chain 5 provides a transmission between a gear 8 keyed to a first heated ironing drum 11 and a gear 9 secured to a second heated ironing drum 12.
  • the gears 8 and 9 differ in diameter to such an extent that the second ironing drum 12 rotates at a somewhat greater peripheral speed than the first ironing drum 11.
  • the gear 9 of the second ironing drum 12 carries a further gear 9 which is connected to a gear through a second chain 14, said gear 10 being secured to a third heated ironing drum 13.
  • the third ironing drum 13 rotates at a peripheral speed greater than that of.the second ironing drum 12.
  • the chain 14 is held under tension by means of a gear 15 of tensioning means 16.
  • the gear 10 of the third ironing drum 13 carries a gear 10 which is in engagement with a third chain 17 led around gears 18, 19 and 20.
  • the gear 18 is acted upon by tensioning means 21, while the gear 19 is secured to a roller 19' (FIG. 1) which determines the advance of a plurality of pretreated and reinforced asbestos aprons 22 travelling in side-by-side relationship round said roller 19'.
  • the gear has the function of keeping the chain 17 in permanent engagement with a plurality of teeth of the gear 19 secured to the roller 19'.
  • the gear 8 carries a gear 8' which drives a fourth chain 23 led around gears 24, 25, 26, 27, 28, 29 and 30.
  • the gear 24 is connected to tensioning means 31 which hold the chain 23 under tension while the gears 25, 26, 28 and 30 are provided to guide the chain 23.
  • the gear 27 is secured to a roller 32 (FIG. 1) which causes advance of a conveyor belt 33 which is in contact with a support plate 34.
  • the conveyor belt 33 has the function of introducing the articles into the ironing machine.
  • the gear 29 is secured to a pressure roller 35 which extends along the first ironing drum 11 and is connected to a pneumatic cylinder 36 which urges the pressure roller 35 against the first ironing drum 11 at a controllable pressure.
  • the pressure roller 35 is provided with an elastic coating so that is is preferably permanently in good contact with the surface of the first ironing drum 11. This pressure roller 35 rotates at the same peripheral speed as the first ironing drum 11 and has the function of retaining and thereby stretching the articles when the leading portions of the articles are gripped by the asbestos aprons 22 and are drawn into the machine.
  • the asbestos aprons 22 move at a speed which is greater than the speed of rotation of the pressure roller 35 and of the first ironing drum 11, for thereby the articles, when reaching the position A in FIG. 1, will be subjected to a first drawing and stretching action ensuring a perfectly smooth contact of the articles with the cylindrical wall of the first ironing drum 11 so that practically a mechanical ironing action is achieved which will last as long as the articles are in contact with said first ironing drum 11.
  • Said stretching action is even still present when the articles have been moved by the asbestos aprons 22 over a deflection roller 38 and travel round the second ironing drum 12 because said second ironing drum 12 rotates at a peripheral speed greater than the peripheral speed of the first ironing drum 11 and because the asbestos aprons 22 run at a speed greater than the peripheral speed of the second ironing drum 12.
