  • Patent number: 7866069
    Abstract: The belt is of those which have a flat configuration and is closed by means of staples (6) or similar. Said belt comprises a mesh fabric (1), with warp (12) and weft (11), in which a plurality of holes (2) of size and determined density are defined, said fabric (1) being covered and thermofixed by a coating (3) of nonslip and temperature-resistant material. The weft (11) has some reinforced areas (4) alternating with some clearer areas (5), in which the weft (11) has a lower concentration of threads or fibres and, jointly with the warp (12), it defines the holes (2).

  • Patent number: 7836617
    Abstract: A separated article of laundry is dragged over a plurality of wheels or belts. The wheels or belts adjust the amount of overhang on each side, making an edge of the article more horizontal. A clamp clamps the edge and drags the article of laundry from the wheels or belts. Resistance, such as by a pinch arm, may assist in untangling the article of laundry as the article is dragged. Sensors adjacent the belts or wheels measure a size of the article of laundry. A folder adjusts based on the size. For example, the types of folds to be made, the placement of runners for folding, or the output sorting are adjusted. The folder may operate more efficiently by providing time for the folder to adjust to the size of the article of laundry prior to feeding from the spreader.

  • Patent number: 7827709
    Abstract: An article is selected and spread from a load of articles. A first clamp moves along a run to remove an article. By changing orientation of the run, articles may be removed from different locations. A second clamp rotates while holding the article. The rotation generally flattens out the article. A third clamp grabs a portion of the article and further spreads the article. This process may detangle or untwist the article. The untwisted article is dragged over a belt. The belt adjusts the amount of overhang on each side. A plate lifts a resulting edge. The article is clamped at that edge and dragged over a roller. The roller moves into contact with a conveyor. The conveyor conveys the article to find a leading edge. The article is then conveyed in a spread position.

  • Patent number: 5172502
    Abstract: A feeding aid for assisting in the feeding of laundry flatwork to laundry processing equipment such as an ironer. The air comprises spaced clamping stations including at least one pivotally mounted clamping wheel which is actuated into a lowered clamping position when a leading edge of a piece of flatwork such as a sheet is sensed beneath an associated laundry sensing device such as a photosensor. After one corner is clamped in place, the sheet leading edge is drawn taut and the opposite sheet corner portion is placed beneath the clamping wheel in a second clamping station. The clamping action of the two stations prevents the weight of the sheet depending from the feed conveyor from causing the sheet to fall by gravity from the conveyor. After a short time delay following clamping by a second clamping wheel, the feed conveyor on which a sheet or the like is clamped is actuated to feed the sheet into engagement with an ironing cylinder or the like.

  • Patent number: 4967495
    Abstract: A feed system for conveying and spreading laundry articles on a conveyor has an air-permeable conveyor having a feed end upon which leading portions of an article are placed for conveyance therefrom. Varying portions of the article to be so emplaced are supported by a feed support element spaced at a distance from the feed end of the conveyor to provide a gap therebetween. A suction duct located generally below the feed end of the conveyor and the feed support element causes air to flow through the feed end of the conveyor to adhere the leading part of the article to the conveyor, and through the space between the feed end of the conveyor and the support element to draw the trailing portion of the article down into a suction duct to stream the article therein by air flow on both sides. An enclosure surrounding the feed end of the conveyor and has a moveable closure member sealing the entrance thereto.

  • Patent number: 4860466
    Abstract: Laundry ironing apparatus comprises sequential ironing rolls each associated with an ironing bed. A first conveyer feeds fresh laundry to the inlet zone of the first ironing roll and a scraper removes the pressed laundry from the periphery of the first roll at the outlet zone of such first roll onto a second conveyer which withdraws the pressed laundry from the outlet zone of the first ironing and feeds it into the inlet of the second roll which is located adjacent to the outlet zone of the first roll. The second conveyer withdraws and feeds in first and second stages, the first of which overlies the second roll and the second of which extends back under the first stage to the inlet zone of the second roll. The combined lengths of the first and second stages are such that pressed laundry is completely withdrawn from the first roll before it is fed to the second roll.

  • Patent number: 4378645
    Abstract: An apparatus for spreading laundry flatwork pieces, such as bed sheets, before feeding them to subsequent processing equipment, such as an ironer and a folder. The flatwork pieces are spread apart by pairs of clamps, there normally being one pair of clamps at the left end, another pair of clamps at the right end, and a third pair of clamps at the center of the apparatus. The spread-out flatwork pieces are blown onto a conveyor for conveying them to the subsequent processing apparatus. Trailing edge sensors are positioned at different levels below the clamps to sense the upward passage of the bottom edge of the laundry flat piece deposited on the conveyor, and a selector switch enables one of the sensors and disables the other, depending upon the speed at which the conveyor is being operated. Proximity switches sense the positions of the clamps. There is an overlying conveyor cooperating with the main conveyor for sandwiching the laundry flat piece as it is moved into the apparatus for stretching purposes.

  • Patent number: 4236330
    Abstract: An ironing installation possessing an ironing machine having two hollow rolls and four heating elements which can be heated by water vapor. During operation water vapor and hot air are sucked into the rolls through holes at the roll shells or jackets. This water vapor-air mixture is expelled to the surroundings through a heat exchanger. Ambient air is sucked into an air infeed line or conduit and infed through the heat exchanger into the internal compartment of a casing which at least partially encloses the rolls and heating elements. Between the aforementioned heat exchanger and an outlet opening or mouth of the air infeed line there is arranged a passage of a second heat exchanger in the air infeed line. A further passage of this second heat exchanger is connected with outlets of the four heating elements.

    Abstract: An ironing machine having two rolls whose axes extend essentially horizontally and are disposed in a common, substantially vertical plane. The rolls can be rotated in opposite rotational directions by means of a drive device. For each roll there are provided two heating elements arranged at different sides of the aforementioned plane. The heating elements have heating surfaces of arcuate cross-sectional configuration. These heating surfaces heating the textile pieces during operation of the ironing machine and pressing such against the rolls. Transport bands or belts serve to guide and transport the textile pieces in such a manner that initially they travel about one and thereafter about the other roll and, thus, follow a predetermined transport path substantially in the form of a figure eight through the ironing machine.
