The present invention concerns an assembly method of the washing group (1) of a laundry washing machine comprising a washing tub (2) and a rotatable drum (3); the tub (2) comprises a rear half-shell (4) and a front half-shell (5) made of plastic and coupled one another in watertight manner, The method comprises: placing the rear half-shell (4) into a first supporting template (6), in a coupling position in which a perimetrical annular rim (4a) of the rear half-shell (4) is faced to the outside of first supporting template (6); fitting/inserting the drum (3) into the rear half-shell (4); placing the front half-shell (5) of the washing tub (2) into a second supporting template (7), in a coupling position in which a major annular rim (5a) of the front half-shell (5) is faced to the outside of the second supporting template (7); arranging the first (6) and second supporting templates (7) so as to put the perimetrical annular rim (4a) of the rear half-shell (4) in abutment against the major annular rim (5a) of the front half-shell (5). The method comprises, before starting a vibration welding process, the step/stage of measuring the starting distance (d1) between the front opening (3a) of the rotatable drum (3) and the minor annular rim (5b)/front opening of the front half-shell (5). The invention concerns also an assembly apparatus for assembly the washing group (1) of a laundry washing machine comprising a washing tub (2) and a rotatable drum (3); the apparatus comprises a first supporting template (6) for the rear half-shell (4) of the washing tub (2) and a second supporting template (7) for the front half-shell (5) of the washing tub (2). The assembly apparatus comprises a measuring device adapted for measuring the distance between the front opening (3a) of rotatable drum (3) and a minor annular rim (5b)/front opening (2a) of the washing tub 2.
摘要:
A roofing membrane includes first and second layers. The first layer includes a low surface energy polymer. A method of installing the roofing membrane includes, along an edge of a first membrane, mechanically removing a portion of the first membrane extending vertically to include the first layer and a portion of the second layer to leave a flap of the first membrane, placing an edge of a second membrane to overlap the first membrane, and bonding the first membrane to the second membrane. The underside of the edge of the second membrane overlies the flap of the first membrane.

An object of the present invention is to provide a method of producing a sheet joined body (5) that is unlikely to make a sheet joined body cause a stepped portion on at least one side thereof and is capable of providing an excellent joining strength to a sheet joined body (5). Provided is a method of producing a sheet joined body (5), which includes a covering step of bringing end faces of sheet members (1,2), which sheet members (1,2) containing a thermoplastic resin, into abutment with each other to provide an abutted portion and covering one side of the abutted portion with a joining member (3), and a joining step of irradiating a portion covered with the joining member (3) with laser light to fusion-bond the sheet members (1,2) and the joining member (3) together, thereby joining the sheet members (1,2) together.
摘要:
Capsules, for example for the delivery of pharmaceuticals, are produced from two films (18) of a water-soluble polymeric material, by deforming the films to form a multiplicity of recesses, and filling the recesses, using two adjacent rotary dies (14, 15; 42) with recesses (16) into which the films (18) are deformed. The dies (14, 15; 42) act as electrodes for welding the films together by dielectric welding to form filled capsules (30). The capsules (30) can be separated from the resulting web either by coating at least one of the dies (14) with an electrical insulator (21), or by transferring the web from the dies (14, 15; 42) to a second pair of dies which cut the capsules (30) free. The polymeric material may be gelatin, or a water-soluble cellulose derivative such as hydroxypropyl methyl cellulose, and may also contain a plasticiser.

摘要:
An optical disc prepared so that, in bonding a disc substrate to a light transmitting sheet, an air bubble incidentally trapped on a bonding surface between the disc substrate and the light transmitting sheet may be reduced in size. An apparatus used for the preparation of the optical disc includes a sheet holding mechanism (32) for holding a light transmitting sheet (19) to be bonded to a signal recording surface (14) of a disc substrate (11), a disc holding mechanism (33) for holding the disc substrate (11) on the light transmitting sheet (19) held on the sheet holding mechanism (32) so that its signal recording surface (14) will face the light transmitting sheet (19), and a thrusting mechanism (34) for thrusting the disc substrate (11) held on the sheet holding mechanism (32) onto the light transmitting sheet (19). The thrusting mechanism (34) progressively thrusts the disc substrate (11) from its center side to its outer peripheral side to drive the air bubble towards the outer peripheral side.
