A parison separation device (30) according to an embodiment includes a cutter (31) with a cutting edge (35), the cutting edge (35) extending in a one direction and facing upward, and a block (33), the cutter being attached to an upper part of the block (33), inclined surfaces (37) being formed on both sides of the block (33) in a thickness direction of the cutting edge (35), each of the inclined surfaces (37) including a component that is inclined increasingly downward as it gets closer to one direction side end, in which the parison separation device (30) is disposed on a discharging direction side of a discharging port of a parison and configured to cut the parison discharged from the discharging port.

This disclosure is directed to a thermoplastic composite material forming method and tooling used to perform the method. More specifically, this disclosure is directed to a method of fabricating large, complex thermoplastic composite part shapes with a consolidation tool having a conformable tooling bladder that heat thermoplastic material in the tool and provide thermoplastic material consolidation pressure in directions in the tool to form a part shape of thermoplastic composite material. A novel tooling concept is used to fabricate large, complex thermoplastic composite part shapes which are not easily producible using traditional methods. The tooling concept employs a consolidation tool that provides a method to apply thermoplastic material consolidation pressure by a conformable tooling bladder that provides thermoplastic material consolidation pressure in directions in the tool that are not achievable by conventional clamshell type molds where the mold parts move in substantially vertical tool opening and tool closing directions.

A production line for manufacturing extruded plates, comprises a conveyor for conveying a semifinished product, an edge cutting device for cutting off an edge area of the semifinished product to present a plate-shaped endless base profile, and a separating device for separating individual plates from the endless base profile. A distance (D) between the separating device and the edge cutting device in the conveying direction is dimensioned such that, between an average temperature T.sub.1 of the semifinished product during cutting of the edge area in the edge cutting device and an average temperature T.sub.2 of the endless base profile during separation, there is a temperature difference T.sub.1−T.sub.2 of 2 K≤T.sub.1−T.sub.2≤15 K. Due to distance (D) within an optimum temperature range, further processing of the cut off edge areas is essentially neutral in terms of installation space.

A method for starting up a production line for manufacturing extruded plates, wherein an extruded semi-finished product comprising a free end is pressed towards a conveying device, wherein the conveying device is configured to pull the semi-finished product to a separating device, wherein a conveyor belt extending in the conveying direction is placed on the conveying device, the free end of the semi-finished product is pressed onto the conveyor belt, the conveyor belt is pulled together with the semi-finished product towards the separating device, and the free end of the semi-finished product arriving at the separating device is introduced into the separating device, while the conveyor belt is pulled away from the semi-finished product upstream of the separating device. This enables a cost-effective production of panels made from the plates.

A winding core with improved beam and hoop strength and diminished friability and method for manufacturing such a core are provided, the method for making the winding core comprising: providing a wood fiber core, applying an adhesive to the wood fiber core, and sliding a tube or sheath onto the wood fiber core.

A separating device (10) for separating a tubular flat material (1) having an actual tube width (1.1), comprising at least one longitudinal separating unit (20) for removing a first edge region (2) and a second edge region (3) of the flat material (1) is provided. In addition, a separating method (100) for separating a tubular flat material and to a system (70) having a separating device (10) is provided.

The present invention is directed to a method of incrementally stretching polymeric film formed from a blown film extrusion process. The present invention is further directed to a polymeric bag formed from an incrementally stretched polymeric film. The incremental stretching is performed on a collapsed polymeric bubble via a pair of intermeshing rollers. The incrementally stretched polymeric film may be stretched only along a portion of its width. The polymeric bag may be a drawstring trash bag with an extended hem where only the extended hem of the bag or the body of the bag comprises incrementally stretched polymeric film.

The present invention relates to a method for manufacturing webs (1) that are intended to be involved in the makeup of a reinforcing ply (2) for a pneumatic tyre (20), said method comprising a preparation step (a), during which a plurality of straight-thread strips (7, 107, 207), which are each formed of a plurality of continuous reinforcing threads (4) that are embedded in a layer of rubber (5), are prepared, a butt-joining step (b), during which said straight-thread strips (7, 107, 207) are butt-joined in pairs to form a straight-thread ply (3), then a cutting step (c), during which the straight-thread ply (3) is inserted into a cutter (8) and the straight-thread ply (3) is severed transversely so as to form webs, wherein, in said method, the frontal width (W3) of the straight-thread ply (3) that is produced during the butt-joining step (b) and then inserted into the cutter (8) is equal to or greater than 50%, equal to or greater than 75%, equal to or greater than 80%, or even equal to or greater than 90%, of the cutter inlet width (W8), whereas the widest frontal width (W7, W107, W207) of the straight-thread strips is less than or equal to 50%, less than or equal to 40%, less than or equal to 25%, less than or equal to 10%, or even less than or equal to 5%, of said cutter inlet width (W8).
