A spacer product (e.g., a fabric) has long and thin stems welded to, interconnecting and extending from, two spaced flexible carrier sheets, such as of thin film. A precursor sheet product may be made by orienting thin, hollow, drawn staple fibers between bristles of a brush, and then fusing a film to the fiber ends by direct welding. The fibers are then withdrawn from the brush as stems with distal ends that are secured to another carrier sheet to form the spacer product.

A device for producing a three dimensional shaped consolidated product. The device includes a rotary drum, defined as a rotary conveyor with a peripheral surface extending in circumferential direction with at least one product shaping area in the form of a cavity on said peripheral surface, the peripheral surface is pervious to air at least in the product shaping area, at least one material feed device to feed a base material into the at least one cavity, a vacuum device designed to generate a negative pressure at least in the at least one cavity, whereby the generated suction is directed towards the interior of the rotary conveyor, and whereby downstream of the material feed device at least one consolidating device is located such that at least a part of the filled cavity is subjected to a consolidating treatment whereby the base material at least partly will adhere to neighboring material.
