Abstract: For the covering of operation patients it has become customary to use a heat reflecting wrapping sheet for protecting the patients against loss of heat. At the operation area, a hole is cut in this sheet, whereafter the usual, sterile cover sheets (20) are placed around the area (16) and spread over the patient and the table. With the invention it is realised that it is advantageous to combine these sheets, viz. in providing the cover sheets (20) as double layer products with associated, separate and edge connected wrapping sheets (22), whereby the sterile personnel can easily arrange for the required wrapping and at the same time form the opening in the wrapping material with full safety for a correct location thereof. It will then only be required that the wrapping sheets (22) be co-sterilized with the cover sheets.

Abstract: A bottle closing cap is disclosed that is openable merely by a finger pressure on a domed top side of the cap, whereby it is possible to provoke an expansion of a depending, axially preslit cap skirt portion of the cap. The cap can resist overpressure in the bottle because the ends of the skirt segments are stabilized against overlapping, e.g. in that at each slit (6) they are shaped with respective counterphased edges (12,14). Hereby the caps will be mountable by a fully conventional equipment and, despite being easy to open, they will resist a considerable pressure in the bottles.

Abstract: A web-like fibrous material consisting of fibres standing on end is produced from a starting material consisting of a web-like fibrous material, in which the fibres are oriented substantially transversely or longitudinally of the web. The starting material is cut into strips which in well-known manner are arranged side by side with the fibres standing on end. It is the object of the invention to eliminate the spaces or interfaces between these strips in a more efficient manner than has hitherto been possible. To this end, the side-by-side pattern of strips is deposited on a moving intermediary supporting surface, on which they are retained by an attractive force directed towards said surface and are at the same time subjected to a spreading action transversly of the strips, whereafter the fibres are deposited at a second depositing position on a moving product receiving surface while at the same time interrupting the attractive force acting on the fibres being deposited.

Abstract: To produce a pile fabric, particularly a pile carpet, a fibrous batt, in which the fibres are transversely oriented, is cut into longitudinal strips which are then turned through an angle of 90.degree. about their longitudinal axes by means of pairs of conveying wires, which run in paths from oppositely located guiding grooves of a pair of input rollers to guiding grooves located side by side in the surface of a depositing roller by means of which the fibres, which are now standing on end, are applied to an adhesive backing.
