A flexible polyvinyl chloride foam member is provided with a permanent profile or shape by use of compressive pressure and radio frequency heating. The resulting article has a higher concentration of smaller foam cells in a portion of higher density than in a portion of lower density.

A strip to be inserted between two elements to cause acoustic attenuation of noise propagating through at least one of the two elements. The strip is made of at least one plastic-based damping material, the strip having an equivalent real stiffness per unit length K'.sub.eq equal to at least 25 MPa and an equivalent loss factor tan .delta..sub.eq equal to at least 0.25.

A method of making bags and the bags resulting therefrom wherein the bags have a top edge and first and second side edges and interlocking rib and groove element at the top edge with a slider straddling the top edge and the slider having a back and downwardly projecting sides with the sides being closer together at a closing end of the slider which extends toward the first edge of the bag and being wider apart at the opening end of the slider which extends toward the second edge of the bag and w...

A profiled clamp connecting two pipes has an articulated clamp strip having sidewalls and a transverse portion connecting the sidewalls and a tensioning closure around the clamp strip. A conical metal ring is arranged in the clamp strip and has a radially inner edge with teeth having free ends positioned on a circle with a diameter that is smaller than an inner diameter of the sidewalls. The conical ring has a radially outer edge resting in a bend between sidewall and transverse part. The first ...

Apparatus is provided for making profiled bars for windows, doors and other frames. The profiled bars are profiled metal cores and profiled facings having angled side flanges. The apparatus includes a carrying frame, a conveyor line for handling the profiled metal cores, an adhesive-applying station in the carrying frame, tangentially extending feeders with conveying members for handling profiled facings to be applied to opposite sides of the profiled metal cores, which feeders are provided on t...

Precise control of the wetting of an edge guide by a coating fluid (i.e., the wetting profile) can be achieved by providing a wetting line below which the coating fluid will wet the surface of the edge guide. Preferably, the height of the wetting line corresponds to a predetermined depth profile of a coating fluid flowing down a coater face. Optionally, a non-wetting surface can be provided above the wetting line, and the non-wetting surface can optionally have a low energy coating provided ther...

Method for aligning and lapping moving profiled sheets fed successively to a roller conveyor, including automatically aligning each successive sheet on the conveyor and maintaining the alignment by downwardly pressing guide rollers, accelerating each sheet in succession off the conveyor onto an adjacent carrier substrate located higher than the conveyor so that the leading end of any succeeding sheet is lapped by the trailing end of the immediately preceding sheet to a predetermined extent.

A profiled wire such as a toothed card roll wire, is made by first fitting together at least two longitudinally extending starting wires each of a predetermined cross-sectional size and each having a longitudinally extending surface region by engaging the regions together transversely and thereby forming a longitudinally extending interface. The fitted-together wires are then bonded together at the interface and the joined wires are subsequently profile pressed, that is deformed by rolling or dr...

A joint for connecting two profiled rods of U-shaped section and having a coupling manufactured from sheet material and comprising two resilient lugs by which the coupling is clamped on the profiled rods to be joined; all the joints occurring in mounting a frame, for example, a longitudinal joint, a transverse joint and a cross joint, can be made by means of only two types of couplings.

A process for forming a profiled element from a generally longitudinally extending extruded sheet-form member having a plurality of transversely spaced longitudinally extended ribs upstanding therefrom is provided. The process includes the step of removing longitudinally spaced apart portions from some of said ribs by means of a transversely acting punching means.
