Patent number: 11492740Abstract: Methods and apparatuses that provide for laundry to be washed and rinsed in a washing device in a state in which it lies spread out on an upper strand of a belt conveyor and, directly thereafter, to be dried in a likewise spread-out state on an upper strand of a belt conveyor. During the washing, rinsing and also the drying operations, the laundry rests on the belt conveyors, which also transport the laundry through the washing device and the dryer. The items of laundry here are washed, and also rinsed, by being sprayed with jets of liquid. The procedure described provides for a compact washing and drying system and is gentler on the items of laundry.Type: GrantFiled: November 2, 2017Date of Patent: November 8, 2022Assignee: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Engelbert Heinz

Patent number: 8615899Abstract: Apparatus and method for the non-contact drying of a web of material. The apparatus includes air flotation nozzles for floating the web, and direct air impingement nozzles for enhanced drying of the web. The nozzle arrangement is particularly well-suited to float and dry light weight webs under moderate to high tension. Increased cushion pressure is created to support the web preferably with the same horsepower as conventional arrangements. The increased cushion pressure pad of the nozzle arrangement allows for good flotation with reduced velocities below about 11,500 FPM. Machine direction wrinkles are removed and the result is positive flotation with no marking on the web or ink build up on the air bars. The nozzle arrangement includes pairs of flotation nozzles directly opposing pairs of direct impingement nozzles. A perforated member can be positioned between flotation nozzles within a pair of flotation nozzles to control return air.Type: GrantFiled: August 3, 2009Date of Patent: December 31, 2013Assignee: MegTec Systems, Inc.Inventor: Michael O.
