<p>Apparatus for use in producing articles (136), each comprising a sheet (10) folded with a first set of concertina folds and transverse to these a second set of concertina folds (180) and two stiff portions (22, 24) attached to opposite outer segments (166) of the folded sheet (10), comprises means (26, 12, 28, 20) to supply the folded sheet (10) and stiff portions (22, 24) and attach them together and maintain the sheet (10) folded before, and/or during al least a part of, the attaching step, the guide means (20) co-operating with flights (14) to push the elements of articles (136) thrilling, the flights controlling the mutual relative position of the separate elements by being stepped and guide means (20) being shaped to vary the positions of the elements relative to the flights (14) during the movement. Supply means for cards (22, 24) are arranged to reciprocate and supply cards alternately from two stores (26, 27). Gluing stops short of all edges of the folded sheet (10). Means (20, 87, 88, 89) control relative positions laterally or longitudinally between said elements during attaching them together to enable precise repetition of their mutually relative positions after attachment. A plurality of channels for simultaneously producing articles (136) have a common motive source (68) and respective means (100) to switch off source (68) from each channel independently, and plug and/or other quick release means (102) to allow quick release and removal of an operative unit (e.g. 12) from one channel with minimum downtime for the other channels.</p> |
