Abstract
In a method of forming plastic sheet material into articles, the sheet is heated and is formed into the article in a mould. The mould 10,12 parts severe the portion of the sheet which is to be formed into the article and at the peripheral edge of the said portion the mould parts squeeze the plastics material (see region 40) to cause it to flow outwardly into a bead cavity in which the material forms into a thickened bead. <IMAGE>
