Abstract: The present invention teaches an apparatus and method for noodle rolling. The apparatus includes a plurality of roller sets vertically arranged one below the other. Each roller set has roller pairs facing each other. The roller gap of each roller set is shifted laterally with respect to the next lower roller set within a range corresponding to the distance between the pair of rollers in the next lower roller set. In this manner, the noodle strip is first guided by the roller periphery in the next lower set before entering the roller gap therein. The noodle strip formed in the uppermost set is progressively rolled through the succession of the following roller sets.

Abstract: A multiple-roll calender for producing thermoplastics films, in which, viewed in the direction of working, a penultimate roll is spaced from the roll which immediately precedes it so that for a period as it travels from said preceding roll to the penultimate roll the material being calendered is not in contact with any of the rolls, and said penultimate roll and a final roll which together define a final working gap, are provided with drive means whereby they can be driven at varying speeds independently of the other rolls.A guide roller may be provided to guide the material centrally into the final working gap or a pull-off roller or pair of pull-off rollers and a constant pressure roller may be provided to guide the material to the final working gap. Alternatively a pull-off roller and a scraper device, defining with the penultimate roll a gap which narrows in a downstream direction may be provided.

Abstract: An industrial-sized briquetting press having two independent bearing housings for supporting the drive shafts of the briquette-forming rolls. One of the bearing housings is rigidly mounted and the other is pivotally mounted to the first by a pivot located midway between the longitudinal axes of the drive shafts. The axes are substantially parallel and the pivotally mounted housing moves in the plane of the axes. The rolls are biased together by hydraulic cylinders. Connecting rods attached to the rigidly mounted bearing housing, slidably passing through the pivotally mounted bearing housing and hollow piston rods of the hydraulic cylinders, and supporting the hydraulic cylinders prevent movement of the briquette-forming rolls in relative longitudinal and lateral directions. The press has no overall frame permitting easy access for repair and maintenance and the pivot is demountable permitting removal of the pivotally mounted bearing housing.

Abstract: The edge knurling of a thermoplastic web must often be carried out at elevated pressure in order to ensure a sufficient knurling depth even after the web has been wound and unwound different times. The prior heating of the web margins permits knurling to be carried out at lower pressures but may adversely influence the crystallinity of a film and also requires an increased amount of energy.The heating of the knurling wheel or tool itself reduces such disadvantages.

Abstract: A multi-roll calender for rubber or synthetic plastics material comprising a pair of rolls mounted at their ends in a calender stand, in which at each of the ends of the pair of rolls, the pair of rolls are rotatably mounted in a bearing block which can be moved to move the pair of rolls together with respect to the calender stand with the gap between the two rolls of the pair rolls maintained constant, one of the rolls of the pair rolls is displaceable relative to the bearing block and to the other roll by having its end engaged in a mounting member which is displaceable in the bearing block, a fixed screw spindle is secured to the mounting member, a rotatable internally threaded sleeve is secured against axial movement in the calender stand and has the fixed screw spindle engagement therein, a drivable worm wheel is rotationally rigidly connected to the internally threaded sleeve, the internally threaded sleeve carries an electromagnetic coupling which can be energised to entrain a spur gear for rotation wi

Abstract: Synthetic plastics film manufacturing plant comprising material feed means, preferably in the form of a screw extruder and rolling mill, feeding a sheet material to a multiple roll calender, the multiple roll calender comprising seven rolls comprising four bottom rolls disposed in an L-shape, one of which four bottom rolls provided in the foot of the L, is an input feed roll, and three rolls disposed one above the other with their axes disposed substantially in the same vertical plane, the lowest roll of said three other rolls being disposed in a horizontal juxtaposition and in rolling contact with the topmost roll of said four bottom rolls and on the same side thereof as the input feed roll.

Abstract: Methd and apparatus for the manufacture of chips or flakes from food, stimulant, or feed materials such as fruits, vegetables, potatoes or the like in which a moist mass of material is deposited on a rotating cylinder. The film is formed on the drum and then removed therefrom, cut into strips and formed into typical chip-like shape, and then removed. A plurality of rotating knives is provided downstream of the cylinder to cut the film into strips and preferably to shape the chips as they are being cut.

Abstract: A material guide jaw, for two co-operating rolls of a rolling mill or calender, particularly for processing rubber or synthetic plastics material, comprising a jaw plate which forms a guide for the material and is so mounted on an intermediate plate which is mounted on a base plate that the jaw plate can be adjusted in three different ways while remaining in the same plane.

Abstract: Hay and similar crop materials can be efficiently compacted and formed into pellets or cubes through a closely coordinated sequence of operations in which the hay picked up from the field is deposited into a feed bin, then advanced by gravity feed uniformly onto a cross feed conveyor which advances the hay through a compaction stage in which the hay is precompressed to bale density, and thereafter it is continuously advanced between a pair of counter-rotating press wheels which further compress and form the hay into dense pellets or cubes.

Abstract: A band passes around two spaced parallel pulleys but behind a drum between the pulleys to flatten dough buns which are placed on the central drum. The central drum is raised or bulging at the center, while thin transverse cross bars are mounted on the drum. The tension of the band may be achieved through adjustment of bearings for the upper pulley, while a motor and speed reducer may be connected to the lower pulley.

Abstract: A continuously operating press for the production of panels, such as chipboards, fiberboards, and the like, and including two cooperating endless plate belts arranged so that the material forming the panels can be conveyed by and be compressed between the belts is also provided with drivable pressure rollers for driving the endless plate belts which are adapted to be moved to an oblique angle with respect to the path of travel of the belts. By moving the drive rollers to an oblique position, lateral displacement of the flexible endless belts surrounding the endless plate belts can be prevented.

Abstract: A method of, and apparatus for manufacturing a flexible plastics hose the method comprising extruding a strip of a first plastics material and a reinforcing element of a second plastics material, winding said strip into a helix around a driven mandrel and bonding adjacent turns together by pressure applied between the mandrel and roller means external thereof to form a tubular wall of said plastics material and simultaneously winding said reinforcing element around the helix of said first plastics material in spaced apart helical turns and pressing it into the first plastics material by said roller means so as to partially embed said reinforcing element into said tubular wall.

Abstract: A calender especially suitable for use with rubber and plastic material. One of two opposed rolls is movable toward and away from the other through direct action of long-stroke fluid actuators that move the bearing boxes on opposite ends of the movable roll. Roll spacing is directly sensed by position-sensitive transducers acting between opposed bearing boxes and responsive to the relative roll positions. The transducers signal changes and initiate correction to retain roll spacing at a set distance. The fluid actuators are controlled to separate the rolls upon power failure and to prevent roll contact in the event work product is not between the rolls.
