摘要:
A shoe device (10) secured to a syphon (12) is disclosed for removing condensate (14) from an internal surface (16) of a rotating cylinder (18). The shoe device (10) includes a shoe portion (20) which is disposed adjacent to the internal surface (16) of the rotating cylinder (18). The shoe portion (20) defines a passageway (22) having an upstream and a downstream end (24,26). A clamp (42) is secured to a distal end (44) of the syphon (12) and is connected to the shoe portion (20) for clamping the shoe portion to the syphon (12). An anchor plate (46) is secured to the clamp (42) and is disposed between the shoe portion (20) and the clamp (42) for anchoring the shoe portion (20). The arrangement is such that in use of the shoe device (10), the condensate (14) flows through the passageway (22) through an aperture (48) defined by the anchor plate (46) and through the clamp (42) into the syphon (12). The shoe portion (20) is fabricated from a material that is softer than the internal surface (16) of the rotating cylinder (18) for inhibiting any wear damage that could otherwise be caused by frictional contact between the shoe portion (20) and the internal surface (16) of the rotating cylinder (18).

Die Erfindung betrifft einen beheizbaren Zylinder zur Aufheizung einer Papier-, Karton-, Tissue- oder einer anderen Faserstoffbahn in einer Maschine zur Herstellung und/oder Veredelung der Faserstoffbahn mit einem zwei- oder mehrschaligen Zylindermantel (2), umfassend eine erste innere Manteleinheit (3) und eine zweite äußere Manteleinheit (4), die durch wenigstens einen mit einem heißen Fluid beaufschlagbaren Hohlraum (5) getrennt sind und Mittel (12) zur stirnseitigen Abdichtung des Hohlraumes (5), ferner eine Trockenvorrichtung. Die erfindungsgemäße Lösung ist dadurch charakterisiert, dass die Mittel (12) ein ringförmiges Element (11) umfassen, welches in axialer Richtung verschiebbar gegenüber der inneren Manteleinheit (3) gelagert ist.
摘要:
A heat transfer roll for producing sheet material, particularly material having a cross-section whose thickness varies across the width of a sheet being formed, includes a journal on which the roll its rotatably supported, and at least two cooling channels at the surface of the roll that can be supplied with various fluids at various flow rates and temperatures. Fluid in the first and second channels flows at predetermined longitudinal positions at the roll surface. The first channel includes cylindrical spiral portions and the second channel includes a circular cylindrical channel located between the spiral portions. A diverter provides hydraulic flow continuity across the second flow channel to first and second portions of the first flow channel. Risers carry fluid radially outward to the flow channels at the outer surface of the roll.
摘要:
A heat exchanger and method for making a heat exchanger including, forming an annular ring of a solid heat conductive mass, the annular ring having a central axis and having axially opposite faces. A plurality of passages are drilled through the annular ring and through the opposite faces to provide passages for the flow of a fluid through the passages and transfer of heat energy between the mass and the fluid. The passages are preferably parallel to the axis and have a circular cross section and are arranged in a plurality of circumferentially spaced sets of passages, each set having a plurality of radially spaced passages.

A laminating machine provided with at least one pair of elastic rolls (3), a heating member (4a) housed in a housing (2), the housing (2) having a recess (21) for holding the heating member (4a), wherein the improvement is to employ a heating member made of an insulator plate having plural grooves parallel to each other, resultantly increasing the radiation area of the heating member (4a).
摘要:
Die Erfindung betrifft ein Siphon zum Abführen einer Flüssigkeit aus dem Innenraum einer Walze bzw. eines Zylinders (2)
mit einem Mundstück (11), das einen Einlass (11.1) zum Aufnehmen eines Flüssigkeitsstromes aufweist, der entlang der Innenfläche des Walzenmantels fließt, ferner einen Auslass (11.3) zum Abführen der Flüssigkeit aus dem Mundstück und aus dem Innenraum der Walze.
Gemäß der Erfindung wird Folgendes vorgesehen:
das Mundstück weist einen zweiten Einlass (11.2) zum Aufnehmen eines zweiten Flüssigkeitsstromes auf, der ebenfalls entlang der Innenfläche des Walzenmantels, aber in Gegenrichtung fließt; dem Auslass ist eine Sperre (20) vorgeschaltet, die bei Eintritt eines der Flüssigkeitsströme in den betreffenden der beiden Einlässe zufolge des Flüssigkeitsdruckes eine Position einnimmt, in der sie den Flüssigkeitsstrom zum Auslass fließen lässt, aber die leitende Verbindung zwischen den anderen der beiden Einlässe und dem Auslass absperrt.
摘要:
Molding apparatus and method for molding of features integral with a base, such as in the production of fastener elements for hook-and-loop type touch fasteners, e.g. by the Fischer process, employs a mold roll (1) formed of rings (9) that have coolant passages (22) formed within the ring components (9) themselves for substantially direct contact with cooling liquid. Axial tie rods (16) compress the mold rings (9) together, contributing to the sealing of the coolant passages and the stiffness of the mold roll. Other sealing means (30) are disclosed. Mold cavities (2), including cavities (2) used for injection molding, and cooling passages (22) formed in either mold rings (9) or injection mold plates by photo-chemical etching, laser machining and other techniques are disclosed. Various machines and methods taking unique advantage of these feature are disclosed, including ring alignment methods.
