Definitions

  • ABSTRACT A machine for drying and ironing fabrics having a central heating cylinder and a plurality of pressure rollers disposed around the central cylinder.
  • An endless canvas belt accompanies the fabric to be treated which belt is guided by the pressure rollers around the central cylinder whereby contact is established with the hot periphery of the cylinder over an arc of at least 330.
  • the object of the invention dealt with comprises a machine for ironing and drying distinct classes of fabrics with the maximum utility of the central heating cylinder surface, due to the canvas belt or apron being in contact with the cylinder throughout about 330 of its wall, and in addition the belt in its zone existing between the loss of contact with the cylinder up to the fabric outgoing roller, or at the upper part of the machine passes very close to the central cylinder whereby the canvas beltof endless type is utilized as an entering support and an outgoing bedding of the fabric to be dried and ironed.
  • Said machine is essentially constituted by two steel plate benches that serve as supports for the five periphery pressure rollers and for the ingoing and outgoing garment rollers.
  • An endless canvas belt circulates pressed by the periphery rollers over the central heating cylinder, so that the fabric to be dried and ironed is situated between the endless cloth and the central cylinder, circulating precisely in the zone determined by the entrance rollers and the outgoing of the fabric.
  • An additional strainer roller provides the endless canvas belt with the necessary tension to prevent side displacements, which may be rectified if produced by actuating one of the hand flywheels which will situate the garment entrance roller that recuperates the side displacement suffered by the canvas belt.
  • the displacement and pressure of the periphery rollers is effected by means of cylinderswith both pistons moved by compressed air.
  • the periphery rollers are dressed with rubber or other elastic material in order to absorb possible inequalities in the fabrics that circulate pressed by said rollers.
  • the assembly is driven by a motor and speed reducer housed in one of the benches, which transmit the movement to the central cylinder through two toothed wheels and a driving chain, the movement being transmitted to the rollers by tangential contact and by the traction effected by the endless canvas belt.
  • two rollers are provided of small diameter at the outlet zone of the garment which, forming an acute angle with the profile, obliges the unfastening of the conducted garment while the canvas belt follows its endless course.
  • the central cylinder is steam heated, the steam entering through an opening in the center of the shaft, and the extraction of the condensed water is effected by means of a syphon tube from the cylinder bottom and through the same shaft opening.
  • the cylinder receives the vapor exclusively adjacent the outer peripheral surface thereof through steam inlet tubes disposed perpendicular to the working surface.
  • Said cylinder consists of two concentric cylinders or jacket between which there is defined a ring-like annular chamber that exclusively receives the steam that strikes directly against the inner surface of the outer wall.
  • Said central cylinder has in the interior of the chamber a helix of steel plate welded or soldered in the outer plate or jacket of the cylinder, which helix during the rotation of the cylinder causes a small quantity of condensed water, produced at each turn or rotation of the cylinder, to flow towards the retention chamber, which retention chamber collects the water in its lowest position and empties same by the outlet tube upon rotating towards the highest position at each turn of the cylinder.
  • FIG. 1 is a front view of the machine with a part of same being shown in cross section.
  • FIG. 2 is a side cross section of the machine.
  • FIG. 3 is a side view of the machine.
  • FIG. 4 is a lengthwise cross section of the cylinder according to a preferred variation of same.
  • FIG. 5 is a lengthwise section of the machine equipped with the cylinder shown in FIG. 4.
  • the benches or side supports 1 are joined by the stays 2 and rotatably support thereon a central hollow cylinder or roller 3, the periphery rollers 4 and the tension roller 5, which rollers engage the endless canvas belt or apron 6.
  • a cloth entrance roller 8 forms with the first periphery roller 4 a feeding support, and an outlet roller 7 or 7 with the two last periphery rollers 4 form a drying platform for unfastening the fabric to be dried from the endless canvas belt.
  • the trays 9 and 10 are the receptacles for the fabric respectively before and after its passage over the ironing cylinder, the fabric being illustrated by dotted lines in FIG. 2.
  • the two hand wheels 11 are for the adjustment of the position of the fabric entrance roller 8, or to determine its parallelism with regard to the central cylinder 3.
  • the piston cylinders 12 are driven by air and automatically actuate the periphery rollers 4 between their rest and pressure positions, which rollers 4 are slidable in their bearing guides 16.
  • a motor 13 drives a speed reducer 14, which transmits the rotation to the central cylinder 3 by means of a chain 17 and a wheel or sprocket 18.
  • the syphonic tubes 15 empty the As illustrated in FIGS. 2 and 5, the angle enclosed by the endless canvas belt in working position on the hot central cylinder 3 permitting this special disposition is approximately 330.
  • FIGS. 4 and 5 illustrate a preferred form for the totatable central cylinder, which in said case comprises a steam chamber comprising a circular roll 19, defined by an exterior cylinder 20 and an interior cylinder 21 and two side plates 22 duly soldered or welded to cylinders 20 and 21.
  • Two hollow shafts 23 and 24 carry radial arms 25 fixed to the interior body 21 of the cylinder.
  • Through the interior of the shaft 23 passes a central steam inlet tube 26 which branches into smaller diameter tubes 27 that project radially of cylinder 3 and discharge steam into the hollow ringlike interior chamber of the cylindrical roll 19 as defined between cylinders 20 and 21.
  • the sides 22 are provided with thermal insulation 32 to prevent heat losses.
  • FIG. 5 shows that the endless canvas 6 belt is provided with outlet rollers 7 and 7" which, owing to their small diameter and disposition, cause an extreme change in the movement direction of the belt, the belt when passing around the roller 7 forming an acute angle, and also result in the belt reach between the rollers 7' and 7" facing downwardly in order to obtain efficient unfastening of the fabric from the belt (as illustrated by dotted lines in FIG. 5) so that the fabric is deposited in the receptacle 10.
