IPC: D21F9/02
Filed: 1991-12-17
Abstract: The twin-wire former is used to produce a web of paper or cardboard. Two wires (endless) wire loops (11 and 12)) together form a twin-wire region in which one wire (12) runs over fixed rails (28) fitted at a distance apart on a dehydration box (18). In the twin-wire region the other wire (11) runs over a few rails (27) which lie opposite the fixed rails (28), are each supported by a pneumatic pressure cushion (24) and can be pressed against the other wire with an adjustable pressure. At least some of the rails (27, 28) may be exchanged for rails of another size whereby especially the width (b, B) of their wire support areas differs.

Title: Loose material filling assembly - has a container in a weighing housing with suction to draw in material and weighing in steps to control material volume
Inventor: JUNGBAUER LEOPOLD
IPC: G01G17/02
Filed: 1992-01-08
Abstract: The assembly to weight and fill a receptacle with loose material carried in an air stream has a weighing scales (10) with a pressure and hermetically sealed housing (12) to contain the receptacle. The material within the housing (12) is measured by a number of force measurement cells (30) for the contents of the scales container (13). The channels (18,22) to fill and empty the system are bonded to the housing, and the container (13) is decoupled from the channels (18,22) through slack membranes, through a disengagement force. Air is drawn out of the housing (12) by a fan (24) to generate an underpressure within the container (13) through the permeable side walls (16) against the supply container, so that air together with carried material flows from the supply container into the scales container (13). Air is pumped by the fan (24) to the interior (56) of the housing (12), to flow through the permeable side wall (16) and the non-return valves (31,32), to give an eddying air current for the material within the container (13) to be emptied (22) into a container. The filling jet (19) and the adjustable blocking plate (20) are arranged so that the inflow carried into the container (13) is directed at 90 deg. to the centre axis (36) to flow radially and evenly to all sides of the circumference. The container (13) has a base, a permeable intermediate base (15), a covering lid (17) and a permeable side wall (16). The lid (17) is fitted with one or more non-return valves which are spring-loaded, for air to flow in during emptying. A beating plate (33) is in front of the air connection (23) for the fan (24), to prevent the air forces affecting the weighing during filling. The container base (14) and covering lid (17) have identical surface sizes. Also claimed is an operating sequence where the blocking plate (20) is operated (35) to regulate the volume flow of material, carrier in the air stream into the container (13), through the cross section of the filling opening (34) and the contents level. The filling channel (18) opening (34) can be set or closed by the blocking plate (20). USE/ADVANTAGE - The assembly is for filling bedding duvets, pillow cases, mattresses and the like with loose flocking material, fibres, flockings, feathers and down, carried in an air stream. The assembly gives a rapid and precise filling action, with a controlled material volume flow.
