The apparatus further comprises a thermal conditioning device (11; 111; 211; 311; 411) configured to act on the dose (6; 106) while the dose (6; 106) is positioned in said at least one mould (5; 105; 205; 305; 405) and before the closed position is reached, by thermally conditioning at least one surface portion (20; 120) of the dose (6; 106) which is distinct from a resting portion (17; 117) of the dose (6; 106) which is resting on the receiving part.
WEB FORMING APPARATUS AND MOLDED BODY MANUFACTURING APPARATUS
A web forming apparatus includes a drum portion and a second web forming unit. The drum portion has an accommodating chamber capable of accommodating fragments, and accommodating powder supplied from a first supplying unit. The second web forming unit forms a second web by letting a mixture containing the fragments and the powder falling from the drum portion accumulate. The first supplying unit includes a storing chamber for storing the powder and an outlet portion provided below the storing chamber. The powder goes out of the storing chamber via the outlet portion. The drum portion has meshes formed in a net demarcating the accommodating chamber. The powder is able to pass through the meshes. The outlet portion is provided vertically over the net of the drum portion.
RESIN-SEALING METHOD
There is provided a resin-sealing apparatus that supplies an appropriate amount of sheet-shaped resin for each workpiece, thereby improving the molding quality of a molded product without production of resin dust, such that no redundant resin is produced on a molded product. The resin-sealing apparatus includes a resin supply part that supplies a sheet-shaped resin by cutting out an amount of sheet-shaped resin appropriate for one-time compression molding from a long resin sheet formed to have a predetermined width and a predetermined thickness depending on an amount of resin required for each workpiece, and a transport part that transports the appropriate amount of sheet-shaped resin supplied by the resin supply part to a sealing mold.
Apparatus for correcting the bending of a molten resin and method of correcting the bending of the molten resin
An apparatus (31) for correcting the bending of the molten resin includes a temperature-adjusting device (32) arranged surrounding an extrusion passage (12) for extruding the molten resin (8) of an extrusion die head (7) along the direction of extruding the molten resin (8), a measuring means (33) for measuring the horizontal position of the molten resin (8) extruded from an extrusion opening (20) of the extrusion passage (12), and a control means (34) for controlling the temperature-adjusting device (32) based on the results measured by the measuring means (33).
Apparatus and method for processing doses
An apparatus including a co-extrusion device for extruding a multi-layer structure having at least one primary layer and at least one secondary layer, so that the multi-layer structure leaves the co-extrusion device along an exit direction; a mould provided with a pair of elements, at least one of the elements being movable towards the other in a moulding direction, so as to compression mould an object from a multi-layer dose which was severed from the multi-layer structure; a transport device for carrying the dose towards the mould; an arrangement for modifying orientation of the dose while the dose is being transported by the transport device, so that the dose is introduced into the mould with an orientation in which the secondary layer extends transversely to the moulding direction.
RESIN-SEALING APPARATUS AND RESIN-SEALING METHOD
There is provided a resin-sealing apparatus that supplies an appropriate amount of sheet-shaped resin for each workpiece, thereby improving the molding quality of a molded product without production of resin dust, such that no redundant resin is produced on a molded product. The resin-sealing apparatus includes a resin supply part that supplies a sheet-shaped resin by cutting out an amount of sheet-shaped resin appropriate for one-time compression molding from a long resin sheet formed to have a predetermined width and a predetermined thickness depending on an amount of resin required for each workpiece, and a transport part that transports the appropriate amount of sheet-shaped resin supplied by the resin supply part to a sealing mold.
Composite automatic production equipment for in-mold placement process
A composite automatic production equipment for in-mold placement process includes a upper stamping mold having a upper die plate and punches, a lower stamping mold having a lower die plate, a punching strip feeding device sending out a punching material strip to the lower stamping mold, an insulating-sheet feeding device feeding out an insulating-film material strip intersecting to the punching material strip. The insulating-film material strip includes a main material strip and insulating sheet sets that are adhesive and detachably arranged along the main material strip. When the upper and lower die plates are closed, the punches punch the punching material strip to form semi-finished products arranged in sequence, and one of the semi-finished products is pressed to adhere to one of the insulating sheet sets. When they are separated, the insulating sheet set on the semi-finished product is torn off from the insulating-film material strip.
SYSTEM AND METHOD FOR MANUFACTURING PANELS FOR USE IN WIND TURBINE ROTOR BLADE COMPONENTS
A system for manufacturing a panel includes a support frame, a first caul plate arranged atop the support frame, a second caul plate arranged atop the first caul plate, and a heating assembly having a housing defining an inlet and an outlet. The housing includes one or more heaters. The heater(s) is configured to generate heat and the housing is configured to generate a first pressurized gas film. Thus, one or more layers of material to be consolidated may be placed between the first and second caul plates and drawn through the heating assembly as the heating assembly applies pressure to the one or more layers of material to be consolidated via the first pressurized gas film in combination with applying the heat via the one or more heaters, thereby consolidating the panel.
Composite Automatic Production Equipment For In-Mold Placement Process
A composite automatic production equipment for in-mold placement process includes a upper stamping mold having a upper die plate and punches, a lower stamping mold having a lower die plate, a punching strip feeding device sending out a punching material strip to the lower stamping mold, an insulating-sheet feeding device feeding out an insulating-film material strip intersecting to the punching material strip. The insulating-film material strip includes a main material strip and insulating sheet sets that are adhesive and detachably arranged along the main material strip.

When they are separated, the insulating sheet set on the semi-finished product is torn off from the insulating-film material strip.
APPARATUS FOR COMPRESSION MOULDING CONCAVE OBJECTS
An apparatus comprises: a dispensing device for dispensing at least one polymeric material; a severing element for severing a dose of polymeric material from the polymeric material dispensed by the dispensing device; a transport element for transporting the dose; a mould comprising a male mould element and a female mould element, the female mould element being positioned above the male mould element.
The transport element is configured to perform a first movement by moving along a path directed from the dispensing device towards the mould, so as to bring the dose to the mould. Moreover, the transport element is configured to perform, in addition to the first movement, a second movement by rotating about an axis, so as to turn the dose from a first orientation with which the dose is received by the transport element, to a second orientation with which the dose is released by the transport element onto the male mould element.
