A shaping head comprises two frames or carousels 22, 24 which can rotate at stations with horizontal parallel axes on the periphery of which there are shafts with the corresponding shaped rollers 36, 38. Change of the rollers in the working position takes place by rotating the rotatable frames. Carriages 100 having idling rollers in which the rollers are carried on the periphery of frames rotating at stations about vertical axes are provided between one shaping head and the next. <IMAGE> |
