摘要:
A sizing device is installed on a downstream side in an extrusion direction of a die. A table having two sizing unit attachment portions (4,5) which are adjacent to each other in a lateral direction orthogonal to the extrusion direction. The table is provided at a device body so as to be laterally movable between a first position where one of the two sizing unit attachment portions is at a production position (a) and the other of the two sizing unit attachment portions is at a standby position, and a second position where the other of the two sizing unit attachment portions (4,5) is at the production position (a) and the one of the two sizing unit attachment portions (4,5) is at the standby position. A sizing unit for production (4) configured to perform cooling and sizing in practice is detachably attached to one of the two sizing unit attachment portions (4,5) at the production position (a) to coincide with an extrusion line. A sizing unit for replacement (5) is detachably attachable to the other of the two sizing unit attachment portions (4,5) at the standby position.

A press-molding machine is taught that may include an extrusion apparatus (10), a transfer apparatus (30), and a molding apparatus (40). The extrusion apparatus (10) may extrude a melted resin into a sheet shape. The transfer apparatus (30) may receive and transfer a sheet material (S) that is extruded from the extrusion apparatus (10) and cut in a predetermined length. The molding apparatus (40) may press and mold the sheet material (S) transferred from the transfer apparatus (30). The extrusion apparatus (10), the transfer apparatus (30), and the molding apparatus (40), are allowed to be independently arranged and constructed.
摘要:
The invention relates to a sensor (1) which is used to record measuring values in a melt (5). Said sensor can be inserted into a bore (2) of the wall (3) surrounding a cavity (4) which receives the melt (5), and is further developed so that it can be withdrawn from the wall (3) when the melt has substantially solidified without much effort and without damaging the sensor (1). The sensor is associated with at least one heating device (9).

The invention relates to a melt blow head comprising a straight row of nozzle apertures (8), arranged in a nozzle block (1). Said nozzle apertures are used to produce filament yarns formed from a melt. Longitudinal blow supply slits pertaining to two slit plates (2, 3) for the passage of the blow air to be supplied to the nozzle apertures in an oblique manner are associated with said apertures, and the melt is supplied to the nozzle apertures by means of at least one distributor (24) in the melt blow head, the at least one distributor being supplied with the melt via a supply line (7). The supply line in the melt blow head leads from a lateral inlet (11) which is connected to a melt pipe (13) by means of a detachable connection (12), via a baffle (10), in an essentially perpendicular direction to the distributor. The nozzle block is fixed in a defined position in relation to the slit plates, and is positioned in such a way that it can be removed from the same in an approximately vertical direction.
摘要:
A die (8) for extruder (1) comprises a first plate (10) mounted on an extruder head (4) of the extruder and provided with first sections (14) of extrusion lands (9) that extend from an entry face (9a) to an intermediate exit face (9c). Also provided is a second plate (11) mounted detachably on the first plate (10) and provided with second sections (15) of the extrusion lands (9) that extend from an intermediate entry face (9d) to an exit face (9b). The first sections (14) have a frustoconical form while the second sections (15) have a cylindrical form.
摘要:
The invention concerns an extrusion head for plastics extruders, said extrusion head comprising a nozzle head (2) arranged axially downstream of a jaw plate (3) in the extrusion direction and formed by an outer cone (5) and an inner cone (6). In an at least approximately radial direction the nozzle head (2) is divided into a main part (9) and a mouth part (10). The cones (5, 6) of the mouth part (10) can be fixed independently of each other to the respective adjacent cone (5, 6) of the main part (9) and interchanged with other cones in a quick-change process.
