Abstract

1427282 Embossing HERCULES Inc 26 July 1974 [13 Aug 1973] 33076/74 Heading B6J [Also in Division B5] A method of making an extensible network structure, e.g. for reinforcing fabrics, or for medical pads, comprises embossing a thermoplastic polymer sheet with a plurality of main ribs 14 interconnected by main webs 16, and forming in each web 16 a plurality of tie ribs 19 interconnected by the webs 20, the tie ribs 19 in some webs 16 being disposed at an angle to a main rib, and the ribs 19 in the other webs 16 being at an angle to the first ribs 19, and drawing the sheet in at least one direction transverse to the main ribs to open the sheet into a network. The main ribs and tie ribs are formed on the same or opposite sides of the sheet. The sheet can be drawn in directions parallel and transverse to the main ribs. The sheet 13 can be fed direct from an extruder to embossing rolls 11, 21 or a previously cast sheet can be used. Also a powdered polymer can be formed into a sheet between the rolls. The cross-sectional shape of the ribs can be, e.g. semi-circular, rectangular, or triangular. The sheet can be in laminated form, with layers of different polymers. The network can be formed by running the rolls 11, 21 at different speeds. Suitable polymers are stated to be e.g. polypropylene, polyesters, polyamides, polyolefins or vinyls.
