Abstract: The invention relates to a method of producing reclosable absorbent garments, in particular absorbent pants, and to the absorbent garments obtainable by said method. Starting from a continuous web (1) of absorbent articles attached side-by-side and with a line of weakening (6) arranged between adjacent articles, a first strip (8) comprising releasably attachable material is applied across the line (6) at one edge (25) of the web. A second strip of flexible material is also applied across the line (6) at the other edge (26) of the web. The web is then folded longitudinally to form a series of closed, joined adjacent articles. The adjacent articles are then partially separated at said line (6) but without rupturing said strips (8, 13), so as to provide a free zone (15) between said strips (8, 13) and the adjacent separated edges of each article. The strips (8, 13) are then joined together across the free zone (15) to form a plurality of joined garments.

The first and second cut edges are brought into engagement, and the first pad is joined to the second pad at the first and second cut edges.

Abstract: In a method of making rolls or strips of material having no flaws except joints a supply of material, such as a roll of fabric is inspected for flaws. If any flaws are discovered portions of the material containing the flaws are cut away. The material is attached together after each portion is removed to create a joint for each reattachment. The portions that are cut away are sized so that the joints will be separated by a multiple of a selected distance from one another. The resulting material can then be fabricated into a panel of window covering material in which all the joints are co-linear along a perpendicular to the surface of the material. The joints are positioned so that they will be on a cut line for subsequent processing. In one embodiment the material is wound into a tubular structure that is cut along the joints to form a panel of window covering material.

Abstract: A welding method controls the welding temperature, welding cycle time, and welding pressure for fabrication of composite structural parts. A welding unit welds multiple plies of thermoplastic prepreg into welded multi-ply assemblies by concentrating welds along the thermoplastic prepreg plies at localized and strategic positions.

The first veneer assembly is raised about its front end by an angle .alpha. into an oblique position so that veneer panels of a subsequent veneer assembly can be threaded into the first veneer assembly using the horizontally reversing feed belt. The first and subsequent veneer assemblies are thereby combined into a veneer-panel strand, and transferred to a continuously operating prepress and press.

Abstract: The present invention provides a method of manufacturing high quality laminated veneer lumber from pre-flattened wood veneer, for such uses as in architecture and furniture, and a method of mass production thereof using veneer which is flattened in advance. A sheet of veneer is first obtained by cutting a log with a rotary lathe or the like, and flattening and cutting the veneer into a predetermined length.

The resultant elongated sheet veneer is cut into a predetermined length to form laminated veneer material having seams. Plural sheets thus formed laminated veneer material are laminated and bonded with their grain directions aligned to form laminated veneer core.

Abstract: A veneer for the veneering of especially curved surfaces has a face veneer formed from thin veneer sheets. The veneer sheets are adhesively bonded along their edges so as to be butted flush and on the side opposite the visible side to a mock veneer which is arranged underneath and which extends over the entire region of the face veneer. To maintain the relative movability between the veneer sheets and the mock veneer, an adhesive is coated on underneath the veneer sheets and is influenced in its setting reaction. In terms of the setting reaction, the adhesive is still reactive over a particular timespan. Thus, when the veneer is finally applied, the adhesive does not tear apart at the joints during a shaping curvature of the veneer because the adhesive in the joint region of adjacent edges of the veneer sheets is set completely.
