In one embodiment the covering has three dimensional multi-layered, cellular vanes, and in another embodiment, the one or more support members are formed of a dark color, the rear support member(s) may be formed of material that is darker than the front support member(s), or vise versa. In another embodiment, the support members, e.g., sheers, have an openness factor, preferably as low as about sixty-five percent (65%) to as large as about ninety percent (90%). Other embodiments include structure, assemblies and methods for controlling the closure of the covering as well as embodiments of bottom rail assemblies. Also provided is a method of manufacturing the covering.

A method and a device with which a bulky decorative piece made of a thermoplastic synthetic resin can be produced. A method for producing a three-dimensional decorative piece made of a thermoplastic synthetic resin includes a step of preparing a decorative piece material including an upper layer that has a thermoplastic synthetic resin film and a lower layer that has a thermoplastic synthetic resin sheet, a step of disposing the decorative piece material on a flat-plate die serving as an electrode, and a softening step of softening and welding the decorative piece material by bringing a flat-plate die serving as another electrode closer to the flat-plate die serving as the electrode, and performing high-frequency dielectric heating while pressing the decorative piece material.

A tube joining device includes a delivery with a first pusher member providing forward movement and backward movement along a delivery direction and delivering a wafer to a first position between a take-out position and a stand-by position, and with a second pusher member providing forward movement and backward movement along the delivery direction in combination with the first pusher member, and the wafer from the first position to the stand-by position.

The invention relates to a welding unit (1) for the welding of film tubes for a waterless toilet, the welding unit (1) comprising welding jaws (2, 3), the welding jaws (2, 3) comprising welding means covers (4, 5), characterized in that the welding means covers (4, 5) are detachably arranged on the welding jaws (2, 3), in particular are detachably connected to the welding jaws (2, 3).

A sealing apparatus including a sealing tool that is movable between an inactive position and a sealing position. The sealing tool includes two actuating elements, each with a respective actuating surface that face each other. The actuating elements are configured to allow the passage of a packaging material therebetween and for transversely sealing the packaging material when the sealing tool is in the sealing position. The actuating surfaces are configured to cooperate with one another to perform the sealing. The actuating surfaces are also configured to cooperate with one another during the change in position of the sealing tool to the sealing position, and for transversely cutting the packaging material during the change in position.

A method for connecting components having a fibre-reinforced thermoplastic plastic includes provision of a first component with a first joining surface, provision of a second component with a second joining surface, flush placement of the first joining surface against the second joining surface in order to form a connection joint, placement of a friction stir welding tool against the connection joint, or a surface directly adjacent thereto, of at least one of the components, softening of the first component and the second component, in each case in a region adjacent to the connection joint, by rotation of the tool, such that the thermoplastic plastic of the two components locally fuses, and movement of the tool along the connection joint for the purposes of connecting the two components by formation of a fusion seam, wherein portions of reinforcement fibres are stirred in to increase the strength of the fusion seam.

A method and a device (10) for welding at least two profiled sections (1) for window or door frames or leaves uses a heating unit (4) introduced between the profiled sections (2, 3) to be joined. At least two heating elements (5, 6) of the heating unit melt the profiled section ends (2, 3) at the end surfaces to be joined. In order to chamfer, in particular remove, a profiled section edge layer (20) of the profiled section ends (2, 3) along the layer surfaces (12, 13) thereof, at least one tool, in particular at least one cutting blade (7, 8), is arranged on the heating elements (5, 6) and is moved such that the material (9) to be melted is displaced into the profiled section interior (11) or into the interior (12) of the profiled section chambers (13). A compression device compresses the profiled section ends (2, 3).

A method and apparatus for sealing a plastic enclosure is provided. The apparatus includes a handle including elements pivotally coupled together at a first end. The apparatus also includes a heating element positioned along an inner surface of an element and connected to a power source where a longitudinal axis of the heating element is oriented parallel with a longitudinal axis of the element. Plastic material including first and second plastic layers is positioned at an interface between the second elements. Upon pivoting the first elements from an open position to a closed position the heating element increases a temperature at the interface to melt the plastic material and form a seal between the first and second plastic layers.

The invention relates to a method and to a device for producing a butt-welded joint between two pipe segments (38, 39) of a pipe (27, 28) made of a weldable plastic material, each pipe segment being held by a gripping means (14, 15), pipe end cross-sections of the pipe segments (38, 39) being machined with the aid of a tool means (11) for forming welding contact surfaces (40, 41), said tool means (11) being disposed in a stationary manner in a separating plane (37) for machining the welding contact surfaces (40, 41) and a separating cut for forming the pipe segments (38, 39) being realised by the gripping means (14, 15) moving the pipe (27, 28) relative to the tool means (11) in the separating plane (37), said separating cut simultaneously serving to form the welding contact surfaces (40, 41).

The present invention relates to a band-like joint tape for covering a butting portion formed by butting an end portion of a one packing film to an end portion of another packing film and connecting the respective end portions of these packing films to each other. The joint tape is comprised of a laminate film formed by adhering a joint layer to a support layer at a peelable state, and covered so as to face the joint portion to the butting portion and heat-sealed so that the joint layer is fused to the butting portion and the fused portion of the joint layer is peeled off from the support layer.
