Abstract

1376291 Sheet forming W HAUPT 22 Aug 1973 [22 Aug 1972 18 Sept 1972] 39718/73 Heading B5A A method of manufacturing strips to retain a conductor in electrically heated mats, comprises forming aheated thermoplastics sheet by differential fluid pressure over a matrix having spaced parallel grooves to form a plurality of arcuate portions 2, cooling the sheet and cutting the sheet into strips at right angles to the grooves. The strips are also formed with arcuate portions 4 and 6, which can be interlocked to allow adjacent strips to be joined together, and slots 8 to accommodate distance elements 9.
