Abstract:
A vibration isolating apparatus damps and isolates vibration generated by an ultrasonic welding machine during ultrasonic welding of components. The vibration isolating apparatus prevents vibration propagation into components and system assemblies that are not intended to be welded thereby preventing unwanted damage to the components and system assemblies.
Abstract:
Machine and method for making air-filled packing cushions from a roll of prefabricated film material (11) having a longitudinally extending inflation channel (19) near one edge of the material and chambers (21, 22) which communicate with the channel (19) through laterally extending passageways (23). The film material is fed from the roll (28) to an inflation tube (52) which extends into the inflation channel, air is introduced into the chambers (21, 22) through the inflation tube (52) to inflate the cushions, and a longitudinally extending seal (89) is formed across the passageways (23) between the channels (19) and the chambers (21, 22) after the cushions are inflated.
Abstract:
A Thermal Bonding Method and Apparatus to thermally bond sheets of fill in a cooling tower fill pack. The apparatus creates a hemispherical joint extending through two fill sheets to provide a substantial joint between said sheets.
Abstract:
A process for producing a surface covering with an embossed printed surface is proposed. A substrate (16) is continuously moved through a production line, and this substrate (16) is first provided, in a printing equipment (12), with a printed pattern and thereafter, in an embossing equipment (14),with an embossed pattern, which is registered with the printed pattern. The printing equipment (12) produces the printed pattern in-line with the production of the embossed pattern. During printing in the printing equipment (12), the printed pattern is stretched or compressed, dynamically responsive to indicators of misalignments between the printed pattern and the embossed pattern, so as to correct or prevent the misalignments.A production line for carrying out this process is also proposed.
Abstract:
Die Erfindung betrifft eine Schweißbasis (11) für eine Schweißvorrichtung (10) zur Herstellung einer Schweißverbindung zwischen Kunststoffrohren (20, 21;34, 35), wobei die Schweißbasis zur Ausbildung einer Stumpfschweißvorrichtung (24) eine elektrische Verbindungseinrichtung (30) zum Anschluss an eine elektrische Stumpfschweißheizeinrichtung (12) und ein Hydraulikaggregat (15) zum Betrieb einer hydraulischen Spanneinrichtung (13) der Stumpfschweißvorrichtung aufweist, wobei die Schweißbasis neben dem Hydraulikaggregat einen Schweißtransformator (38) aufweist, der mittels einer elektrischen Verbindungseinrichtung an eine elektrische Heizwendelheizeinrichtung (14) anschließbar ist.
Abstract:
The invention discloses a method for welding tubular elements (10) that utilizes a method for defining the outline of sections of tubular elements which comprises the steps of: arranging a scanning device (1) and defining a respective scanning resolution (RS); arranging a tubular element (10) that has outlines (11); defining a framing position (PI) for scanning an outline (11) on the scanning device (1); scanning the outline (11) so as to obtain an image (20) of the outline (11); defining edges (21) of the section in the image (20); deforming the edges (21) as a function of the outline (11) so as to define a refined image (20p); scale mapping (M) the outline (11) starting from the refined image (20p) as a function of the resolution (RS); arranging at least two tubular elements (10) comprising respective zones to be welded (4) facing each other; heating the zones to be welded (4); coupling the zones to be welded (4), one to the other; making a groove (19) in each zone to be welded, of the tubular elements (10), prior to the heating step, the groove (19) being made by means of a removal procedure on the perimeter of the outline (11) of each tubular element (10), in which removal is carried out as a function of the scale mapping (M). The invention also discloses an apparatus for welding tubular elements (10) for implementing the method disclosed.
Abstract:
A method of manufacturing a device having a first elastomeric portion (200) and a second elastomeric portion (204), the second elastomeric portion being formed into a non-planar shape, i.e., a vaginal discharge collection device (214) that is formed of an elastomeric rim (200) and a flexible film reservoir (202). The method includes the steps of loading a rim (200) into a carrier plate (16), laying film (204) over the rim, heat sealing the film to the rim, preheating the rim and film, drawing the film into a chamber by creating a vacuum to form the collector, and removing the collector from the carrier plate.
