Definitions

  • the invention relates to a device for removing creases from or straightening individual pieces of fabric, such as sheets, by means of a current of air before said pieces of fabric are fed into an apparatus for handling them, e.g. a mangle.
  • the invention has for its object to provide a device for straightening, stretching or spreading pieces of laundry, cloth or like pieces of fabric by means of a current of air, which device has a particularly simple construction. It consists in the provision of a well or shaft opening in front of the inlet opening of the apparatus for handling said cloth or pieces of fabric and a device for the production in said shaft of a current of air directed away from said inlet opening.
  • the apparatus is a mangle for ironing pieces of laundry, e.g. sheets, towels, etc. and if said mangle is provided with a straightening plate or bar mounted in front of its inlet opening said straightening plate or bar may at the same time form the upper rear edge of a narrow vertical shaft, which is open at its upper end and is connected at ornear its lower end to a suction conduit.
  • a sheet must be ironed, said sheet is brought with a marginal portion into the mangle or the feeding members thereof whilst the suction conduit is closed and the sheet is drawn over the upper opening of the shaft or pushed into the latter. If thereupon the suction conduit is opened the sheet is sucked down into the shaft.
  • the shaft near its upper edge with an inlet aperture in one or each of its two long vertical walls and to connect said inlet aperture to a pressure conduit. It is also possible to so construct the shaft as to bound one or each of its long sides by two spaced apart walls and to connect the space between the or each pair of said walls to the pressure side of a fan. If desired, valves may be provided, which are in at the upper end of the shaft. ing of the current of compressed air may also be efiected 2 adapted to open and to close the or each inlet aperture for admitting compressed air into the shaft.
  • Fig. 1 an elevational sectional view
  • Fig. 2 partly a cross sectional view and partly a plan view
  • FIG. 1 designates a mangle having in front of its inlet opening 3 a so called straightening plate or bar 2.
  • a vertical tube-shaped well or shaft 4 having double long walls 5, 5a and 6, 6a. its upper end and is connected near its lower end through a grid 7 to a space 8, which is connected at its later'al ends 9 to the suction conduit 10 of fan 11.
  • the walls 5, 5a and the walls 6, 6a confine spaces 12, 13, which at '14 communicate with the pressure conduit 15 of said fan 11 and at their upper ends at 16 with the upper end of the shaft 4.
  • the straightening plate 2 and a corresponding plate 17 or a roller cover the spaces 12, 13 at their upper ends.
  • a slot 18 is left free between said parts 2 and 17.
  • a sheet to be ironed by the mangle 1 is fed with its front edge into feeding members (not shown), which move the sheet towards the inlet opening 3 of the mangle.
  • the rest of the sheet is pushed or sucked into the shaft 4 through the slot 18.
  • the current of air produced in the shaft 4 pulls the sheet downward in such a manner that present creases or overfolds are straightened or stretched before said creases or overfolds reach the edge of the straightening plate 2 during the movement of the sheet.
  • a device for smoothing laundered articles comprising a box-like outer container having a horizontally extended base and a vertically extended narrow upper section, said upper section having a top with a long, narrow inlet-outlet opening for the insertion of a laundered article except for an edge of said article which is led to said mangle, an inner box-like container similar in shape to said outer box-like container, said inner container having its upper section open at the top to receive said part of article inserted in v the inlet-outlet opening of said outer container, and an air moving means connected to said inner container and adapted to move air down said vertical upper section of said inner container, said air moving in the opposite direction to that in which said article moves, out through said inlet-outlet opening to said mangle, whereby said laundered article is stretched and smoothed by said passage of air.
  • a device as claimed in claim 1 in which said inner container is arranged in said outer container so as to leave 1 a free airway between said containers, said airway opening into the upper end of said inner container.
  • a device as claimed in claim 2 in which the air moving means is a fan having a pressure end and a suction end, said pressure end being connected to said horizontal base section of said outer container and said suc tion end being connected to said horizontal base section of said inner container.
  • a device as claimed in claim 1 in which the horizontal top of said outer containers upper section has a straightening plate intermediate said inlet-outlet opening and said mangle, said articles being drawn over said Said shaft 4 is open at straightening plate'to'the mangle and against'the opposing force of the air movement in said article in said inner container. 7 s
  • a fabric straightening device comprising wall means defining a hollow vertically extending well terminating at its upper end in a narrow elongated opening disposed adjacent to and in front of said ,fabric receiving surface at substantially the same elevation as said surface and extending substantially the full length'of said surface, saidopening being open directly to the atmosphere, said wellextending downwardly from saidvopening substantially to the floor and having an air discharge outlet at its lower end, and-air moving means communicating with said discharge outlet and opera tive to draw atmospheric air into said well through said opening and down through said well and thereby drawthe unengaged portion of said fabric sheet down into said well so as to hang freely down in said well, the flow of air down through said well causing said
  • a fabric straightening device comprising means defining a narrow elongated opening disposed adjacent to and in frontof said fabric receiving surface substantially the same level as said surface and extending substantially the full length -of said surface, said opening defining means comprising a straightening lip, wall means defining a deep well extending downwardly from said opening and having an air discharge outlet at its lower portion, said opening at the upper end of said well being open directly to the atmosphere, air exhaust means connected with said outlet to draw.
  • said feeding means drawing said fabric sheet upwardly out of said well and over said lip, and means defining an air inlet into said well below said lip so that air is drawn down on opposite sides of said sheet to cause said sheet to flutter and means, and having a straight forward edge, wall means defining a vertically extending deep well terminating at its upper end in a narrow elongated opening disposed immediately in front of said straightening surface at substantially the same level as said surface and extending substantially the full length of said surface, said openingbein'g open directly to the atmosphere, said-well extending downwardly from said opening 'a distance at least several times the thickness of said well in a direction transverse-to said opening and having an air discharge outlet in its lower portion, and air moving means communicating with said discharge outlet and operative to draw atmospheric air into said well through said opening-and down through said shaft and thereby draw the unengaged portion of said fabric
