Equipment for forming tubular bodies from flat flexible sheet materials has a mould 1 against which the sheet material is shaped by compression means 2, 3 and 4. The sheet material enters the equipment at one end and is transported through the machine by conveyor belts 14, to leave the machine at the opposite end. An adhesive applying device 15 associated with the start of the belts 14 applies adhesive to one edge of the sheet material and the edges of the sheet, after forming of the tubular body, are compressed between tubular rollers 19, 20 to bond the edges of the sheet together. The rollers 19, 20 also assist in extracting the sheets from the equipment. <IMAGE> |
