A panel (1) comprising a front surface (2) shaped to simulate a framed-up panel is manufactured by forming a main panel member (4) from a main substrate (7) laminated with a main veneer sheet (10). A front surface (5) of the main panel member (4) is formed and shaped to simulate a pair of stiles (12) and an infill panel (14) and to define rail receiving surfaces (15) at opposite ends of the infill panel (14). Rails (16) each formed from a secondary substrate (20) laminated with a secondary venee...

A panel, particularly a floor panel, which exhibits a spring on at least one side and a groove on the opposite side, which features are designed in complementary fashion such that several panels can be connected by inserting one panel into the other, while the spring/groove connection is provided with interlocking portions which prevent the two panels from sliding against the connecting direction, is distinguished by the fact that the spring exhibits a slit that runs parallel to the upper side o...

A flooring panel or wall panel (20) is provided with a tongue (1) and a groove (2) each comprising cooperating locking means in the form of ribs (11, 12) and grooves (9, 10). The locking means of the upper side and lower side of the tongue (1) and groove (2) respectively are arranged staggered in an insertion direction in which the two panels to be joined to each other are joined to configure a firm joint between two adjoining panels at which an additional surface portion (31; 32; 51) step (31) ...

A panel, particularly a floor-covering panel, is provided that has separate horizontal and vertical locking structures. The panel has a first side edge and a second side edge. The first side edge has a groove and a locking lip, and the second side edge has a tongue and a locking tongue. The first side edge of one panel interlocks with the second side edge of another panel without adhesives or fasteners such that the tongue and groove form a joint that provides a vertical interconnection lock and...

Panel forming apparatus for producing a curved panel from a straight panel disclosed has first and second pairs of wall-indenting dies (281, 282 and 283, 284) spaced from one another to receive therebetween each inclined sidewall portion of a straight panel. A hydraulic motor (M1) is coupled by a power train to rotate said first pair of wall-indenting dies. A hydraulic motor (M2) is coupled by a second power train to rotate the second pair of wall-indenting dies. A third pair of wall-indenting d...

A wall panel comprising a central layer of fabric having glued thereto on one side a layer of veneer wood or imitation leather and provided on the other side with plastic material secured to the fabric by hot pressing so as to impart to the wall panel the geometric embossed form of the pressing die.

An insulated panel for use in fabricating building structures wherein fastening strips are utilized in combination with rivets to create a panel that is rigid and has no metal to metal contact between a metallic inner wall and a metallic outer wall.

A method of joining together in sandwich manner a unit comprising a first metallic sheet and a second metallic sheet with a cellular metallic core between them is effected by welding the first sheet to suitable prominences on the cell walls of the core and brazing the second sheet to the core in such a way that brazing material enters and so reinforces the corners of the cells but is not permitted to flow on to the first sheet. The unit constitutes an acoustic panel in which the first sheet is a...

A panel lock is provided for securing two paperboard panels in face contact. A notch is provided in the edge of one of the panels, and a generally T-shaped locking tongue is hinged to the other panel along a fold line substantially coinciding with the base of the notch. The locking tongue is folded through the notch so that the cross-bar of the T-shaped tongue lies against the surface of the notched panel most remote from the panel supporting the tongue.
