Abstract: The invention concerns a procedure and a mechanism for washing textiles in a tub-type washing machine with a horizontally arranged tub, in which during the washing and rinsing cycles the tub is driven with a rotational velocity at which the centrifugal velocity at the tub case is between 0.4 and 0.95 g, so that the textiles are repeatedly lifted up, and then fall in a trajectory onto the lower portion of the tub, and that between the washing and rinsing cycles and after the last rinsing cycle the tub is driven at spin speed, and in which the washing or rinsing liquid is led into the suds container and is supplied to the textiles by immersing the tub in the liquid or by at least one spray nozzle spraying into the tub continuously or at intervals.
Abstract: A tunnel-type batch washing machine has an outer tunnel-forming housing tube centered on a horizontal axis and provided internally with a helical wash screw rotatable in the tube about the axis and having a plurality of flights defining axially spaced compartments. A generally cylindrical sleeve is fixed to this screw and is coaxially received within the tube between the screw and the tube. A treatment liquid is flowed axially in one direction through the housing and respective batches of articles to be washed are held in the compartments between the flights. For washing the screw is oscillated back and forth about the axis through substantially more than 360.degree. to agitate the articles in the liquid. Periodically the screw is rotated about the axis through substantially more than 720.degree. in a rotation direction to advance the batches axially opposite the direction of liquid flow.
Abstract: A method for dyeing of textiles in a liquid bath and an apparatus for performing the process which effectively stirs the dye bath resulting in a more homogeneous color distribution in the bath. The method also results in a faster drying process of the goods. Thus, the dyeing processing time has been reduced while the dyeing of the goods has been made more uniform.
Abstract: The specification describes a procedure for the washing of clothes in a washing machine with a horizontal, perforated, driven tub arranged inside a housing, in which during the washing and rinsing cycles the clothes are repeatedly lifted up, and then fall in a trajectory onto the lower portion of the tub, and are then distributed and pressed against the tub wall, largely without unbalance, as the tub velocity is gradually increased, and are then centrifuged as the velocity is increased further.
Abstract: This invention relates to a wash unit for dry cleaners and the like. According to the invention the wash unit includes a drum which is rotated by utilizing part of the energy of the circulating water, which passes through the outer perforated wall of the drum.
Abstract: A batch washing machine comprises an imperforate drum open at both ends and mounted for rotation about a substantially horizontal axis. A conveyor worm having an imperforate helical surface is rigidly mounted in the interior of the drum to divide same into a plurality of individual chambers. Washing media is fed to the chambers by means of a pipe disposed on a central axis of the drum, the pipe being sub-divided into individual pipe portions by the helical surface of the conveyor worm, with each pipe portion including at least one outlet aperture communicating with a respective one of the chambers. At least one emptying aperture is provided in the drum for each chamber and through which washing media can be discharged from the chamber. During washing, each chamber is separated from the other chambers, so that the machine can wash different types of washing at the same time.
Abstract: An improvement on conventional clothes dryers including a spray nozzle, a control valve, and a water line coupled to an existing water source. The touch-up spray is used for removal of wrinkles from clothing and fabrics and permanent press clothing in particular without removing a garment's factory set creases. The apparatus may also include a water heating unit for spraying water of a selected temperature or steam. The apparatus may further be provided with a liquid additive dispenser for dispensing static electricity removal agents and clothes softening fluids.
Abstract: Disclosed is a device for adding and/or removing fluid media in a rotatable drum, such as a rotating washing machine drum, comprising a pair of flanges attached to the outer periphery of the drum and spaced apart to define an annular space extending around the drum, an elastically yielding sealing member attached to each flange and extending inwardly into the annular space where their sealing lips abut to form a seal in a generally radially extending sealing plane, fluid passageways extending through the wall of the drum in the region between the flanges, and means positioned in the sealing plane for spreading the sealing lips apart, preferably a flat tapered conduit or one or more tapered disks. In another embodiment a sealing device is disclosed having only one flange and one elastically yielding sealing member in association with an annular plate fixed to a partition wall through which the drum extends.
Abstract: This disclosure teaches a process and machine particularly suited for dyeing at a low liquid to goods ratio synthetic fibers, such as polyesters, orlon, and nylon, or blends of such with cotton, where further there are minimal risks of thermal shock, cracking, or bruising during cool down.The disclosed apparatus has a tub enclosing the dye bath, spaced air inlet and outlet openings for the tub, and a blower for forcing air through these openings and in close proximity to the dye bath and its surface. This forced venting of the dye bath enclosure with air effectively cools the dye bath quickly but uniformly during the cool down phase of the dye cycle.Preferably, dampers at the inlet and outlet openings can be closed to minimize the unwanted escape of vapors from the dye bath during the heat up and/or boil phases of the dye cycle; and further can be opened controlled amounts for varying the volume of airflow over the dye bath during cool down.
Abstract: A tunnel-type commercial-duty washing machine has a horizontally elongated housing subdivided by a succession of partitions into a succession of compartments each provided with a generally cylindrical foraminous drum. Each drum is provided with a respective foraminous scoop formed from a first generally cylindrical section having an edge attached to the outer wall and extending between the end walls of the drum and a second generally frustoconical section forming a continuation of the cylindrical section and having a side edge joined to one of the end walls over a major arc of the periphery of an aperture in one of the end walls. Thus the drums may be oscillated back and forth to agitate clothing, but when rotated through greater than a predetermined angle the scoop will pick up the articles of clothing in the drum and displace them axially out of the drum.
Abstract: A laundry machine for washing clothes having both a wash and extraction operation. There is included a rotatable drum for tumbling the clothes and means for introducing liquid into the drum. Means are also provided for producing a vacuum or negative pressure to which is connected two active baffles located on opposite sides of the interior of the drum to withdraw the liquid and air from the drum and two inactive baffles therebetween. This arrangement improves the washability of such a laundry machine.
Abstract: A laundry machine and method for washing clothes having both a wash and extraction operation. There is included in the machine a rotatable drum for tumbling the clothes and liquid introduction means are provided for introducing liquid into the drum at the average rate of 0.5 to 3 gallons per minute during the wash operation. Means are also provided for producing a vacuum or negative pressure to withdraw the liquid from the drum during the wash operation at a rate sufficient to prevent a bath type washing action, then at the end of the wash operation stop the introduction of liquid into the drum and continue the negative pressure to withdraw the liquid during the extraction operation.
