Apparatus and method for cutting and/or crimping wrapping material
A cutting, or crimping, apparatus having first and second opposed jaw members which are mounted on a frame and are movable relative to each other from a first axial position to a second axial position along an axis so as to respectively cut, or crimp, wrapping material extending between adjacent articles wherein at least one of the jaw members is rotatably mounted to the frame such that it is rotatable from a first rotational position to a second rotational position, in the first rotational position the jaw members are movable relative to each other along a first said axis and in the second rotational position the jaw members are movable relative to each other along a second said axis that is inclined relative to the first axis.
Method of manufacturing contoured objects by radio frequency welding and tooling assembly for same
A method includes compressing a non-dielectric, elastically-deformable component, a wire mesh component, and a dielectric, contoured object between first and second forming tools. Once the components are compressed, radio frequency energy is supplied to the first forming tool, thereby causing a radio frequency electromagnetic field to be generated between the first forming tool and the wire mesh component that results in a contoured weld of the contoured object. A tooling assembly is configured to carry out the method.
CONDUCTION WELDING
A welding apparatus for a fibre reinforced resin based material comprises an elongate flexible heat conductive strip and an elongate heat sink extending around at least a portion of the perimeter of the conductive strip. The elongate heat sink is divided into a plurality of segments wherein adjacent segments can move relative to one another.
Deformed Web Materials
Deformed web materials are disclosed. The web materials have discrete deformations formed therein. The deformations may be features in the form of portions of a web with apertures therein, protrusions, depressed areas, and combinations thereof. These features may extend out from the surface on one side of the web, or from both of the surfaces of the web. Different features may be intermixed with one another.
Method for applying a seal to a plate
The invention relates to a method for applying a joint (2, 102) onto a plate (3), in particular a plate having shape defects. An edge of interest is defined on a portion of the plate (3) onto which the joint (2, 102) is intended to be applied. The plate (3) is then placed on a tool (4, 104) comprising a supporting element (5, 105) made of solid material and a supporting element (6, 106) made of flexible material, in such a way that the edge of interest rests on a portion of the supporting element made of flexible material. While the joint is applied onto the edge of interest, the plate is maintained in a predetermined reference position and the element made of flexible material is pushed against the plate, perpendicularly to an outer surface of the element made of flexible material, the outer surface being opposite to the surface on which the edge of interest rests.
APPARATUS AND METHOD FOR WELDING COMPOSITE THERMOPLASTIC MATERIALS
An apparatus for welding composite thermoplastic materials comprises a welding member configured to receive the composite thermoplastic materials there at; and a controller for controlling a temperature by which composite thermoplastic materials received at the welding member are heated, the controller being configured to provide a plurality of heating cycles during which the composite thermoplastic materials are welded. There is also a method for welding composite thermoplastic materials, the method comprises receiving the composite thermoplastic materials at a welding zone; and applying a plurality of heating cycles to the composite thermoplastic materials at the welding zone.
Machines for transferring a preformed functional film onto an ophthalmic substrate and method for producing an ophthalmic lens comprising a method for transferring the preformed film onto the substrate
A machine for transferring a preformed functional film onto a curved face of an ophthalmic substrate, including: a first device for receiving and holding the substrate; a second device for receiving the film, the first device and/or second device configured to hold the film by applying a pressure force to the periphery thereof; a first mechanism for moving the devices, configured to place the curved face such that it faces the film, a second mechanism for moving the devices, configured to bring into contact the center of the film with the center of the curved face and to apply the film with the substrate to radially spread, from the center of the film up to the periphery thereof, a conformal contact between the film and the curved face; and a control and command unit configured to control at least the second mechanism when the film and the substrate are in contact.

Heat-Sealing Apparatus and Method for Forming Composite Heat Seal Structure
A heat-sealing apparatus for forming a composite heat seal structure, includes a belt conveying, heating and press bonding portion configured to convey and heat a heat seal material to form a band-shaped peelable seal, and a die roll press bonding portion configured to add a linear peelable seal to the band-shaped peelable seal in a longitudinal direction of the band-shaped peelable seal for forming the composite heat seal structure.
METHOD FOR PRODUCING A PART USING A HEAT-SHRINKABLE SLEEVE
A method for producing a part. This part including a surface portion whereon is positioned an element to be assembled via an adhesive on the surface portion. The method includes the steps of: mounting a sleeve of heat-shrinkable material around at least one portion of the element on the part, heating of the sleeve in order to shrink it and thus to apply an application force of the element on the surface portion, hardening of the adhesive, and removing the sleeve.
