摘要:
A method for forming a geomembrane liner testable for leaks by securing adjacent panels together with the conductivity of the lower surface of an overlying panel broken along a line adjacent the panel overlapping edge, and the overlapping edges sealed along the line. A heat welder has slots for the overlapping panel edges, with a heated wedge between the slots and having a projection to break the conductivity of the overlying panel bottom surface as it passes the wedge. The slots merge to press the liner edges together to heat weld them along the line of broken conductivity as the welder is moved along the panel edges.

The invention relates to a mounting device for the simultaneous welding of a plurality of sensor holders along a horizontal line of a bumper. Said mounting device can be adapted to different dimensions of bumpers and has one or two freely radiating diode lasers for each sensor holder. A holding-down element is arranged downstream thereof in the direction of emission, which includes a gripper for receiving the sensor holder and a holding-down element for introducing a contact pressure, said holding-down element being permeable in partial areas for the laser radiation of the diode laser.

An apparatus and related method of utilizing articulating vacuum plates to manipulate a film or polymeric sheet and form a three dimensional article is provided. The apparatus can be in the form of an articulating vacuum plate system which includes one or more plates or mold parts that are configured to support a sheet, constructed for example, from a polymeric film, in a two dimensional configuration or a three dimensional configuration in a first mode. The apparatus is constructed so that the plates and/or mold parts can articulate or move so as to reconfigure the sheet from a generally planar configuration into a second three dimensional configuration in a second mode for further forming, optionally while the plates and/or mold parts apply vacuum to the sheet while the plates and/or mold parts articulate, so that the plates and/or mold parts bend or otherwise manipulate the configuration and shape of the sheet.

A method of bonding materials may comprise defining a bond interface between two materials in a cure zone on a surface of an object, and non-conductively heating the bond interface without directly heating the surface outside of the cure zone. Non-conductively heating the bond interface may involve applying microwave radiation to the bond interface.

A one-piece paper container is formed by cutting and pressing a single-layer coated paper into an unfolded container body and cover, then steaming to soften one of the surfaces thereof and thermoforming with an upper and lower moldings at 120° C.˜160° C., combining a coating film covering on a plurality of coincided surfaces at the corners and forming enhanced surfaces with protrusions at on the container body and the cover in the meantime, therefore forming a strong structure. Finally, conducting a moisture examination to decide if the product is qualified or not, so as to ensure safety for the consumers.

An induction sealing device for heat sealing packaging material for producing sealed packages of pourable food products and fed in a first direction, the sealing device having an inductor device which interacts with the packaging material by at least one active surface; a supporting body made of heat-conducting material and housing the inductor device; an insert made of magnetic flux-concentrating material and housed in the supporting body; and a member made of plastic material, and having at least a first portion interposed, in the first direction, between the supporting body and the insert so as to be at least partly surrounded by the supporting body.
摘要:
Systems and methods for joining polymeric materials together may use lasers or broadband infrared heat sources. The polymeric materials are arranged in an overlapping manner and then are exposed to the heat producing radiation for a sufficient time to join the polymeric materials together at the overlapped area. Such systems and methods may avoid the need to add an energy absorbing dopant to the materials being joined. Such systems and methods also may be used on transparent materials.

The invention relates to a device for welding profiled parts (8), in particular plastics profiled parts, having at least one welding head (1) that can be positioned in a predetermined or predeterminable target welding position (6) relative to another welding head (1, 9) and/or relative to a holding device. According to the invention the welding head (1) and/or a part of the welding head (1), that comprises at least one heating element, such as a heating plate, for melting the profiled parts, can be positioned and/or is movable in accordance with at least one dimensional variation of at least one of the profiled parts (8) from a target dimension in a spatial tolerance range (5) around the target welding position (6).
