Abstract

E' descritta una apparecchiatura di piegatura di un foglio di cartone ondulato in cui un foglio di cartone ondulato (10) non piegato che è stato sottoposto a procedimenti di fustellatura e piegatura può essere alimentato e ripiegato lungo le linee di piegatura, detta apparecchiatura comprendendo: un supporto cilindrico (16) esteso lungo la direzione di alimentazione di detto foglio di cartone ondulato (10) almeno sulla zona includente la posizione di inizio di piegatura alla posizione di fine piegatura; una pluralità di fori passanti (16a) definiti lungo la direzione longitudinale di detto supporto (16) in modo da fornire una depressione entro detto supporto (16); e un nastro a ciclo chiuso (20) avente una pluralità di fori passanti (20a) definiti lungo la direzione longitudinale con intervalli predeterminati tra essi e estesi attraverso una coppia di rulli (22, 24) supportati girevolmente su ciascuna estremità longitudinale esterna di detto supporto (16); in cui detto nastro a ciclo chiuso (20) è concepito per muoversi esternamente lungo la superficie di detto supporto (16) avente fori passanti definiti in esso (16a) durante la sua corsa verso monte, per cui detto foglio di cartone ondulato (10) può essere alimentato mentre è saldamente immobilizzato sulla superficie del nastro a ciclo chiuso (20) nella corsa verso valle con l'ausilio dell'azione di aspirazione esercitata in detto supporto (16). Nell'apparecchiatura di piegatura dell'invenzione, non solamente può essere efficacemente impedito slittamento del foglio di cartone ondulato (10) fuori dal nastro trasportatore (20) durante l'avanzamento o la piegatura, ma inoltre può essere impedita macchiatura dei fogli seguenti (10) a causa dell'inchiostro di stampa trasferito al nastro (20) dai fogli trattati, e pertanto può essere ridotto il numero dei fogli suscettibili di essere scartati come articoli inaccettabili.A folding apparatus of a corrugated cardboard sheet is disclosed in which an unfolded corrugated cardboard sheet (10) which has undergone punching and folding processes can be fed and folded along the folding lines, said apparatus comprising: a cylindrical support (16) extended along the feeding direction of said corrugated cardboard sheet (10) at least on the area including the position of beginning of folding to the position of ending folding; a plurality of through holes (16a) defined along the longitudinal direction of said support (16) so as to provide a depression within said support (16); and a closed cycle belt (20) having a plurality of through holes (20a) defined along the longitudinal direction with predetermined intervals between them and extended through a pair of rollers (22, 24) rotatably supported on each external longitudinal end of said support (16); wherein said closed loop belt (20) is designed to move externally along the surface of said support (16) having through holes defined in it (16a) during its upward travel, whereby said corrugated cardboard sheet (10) it can be fed while it is firmly immobilized on the surface of the closed loop belt (20) in the downstream run with the aid of the suction action exerted in said support (16). In the folding apparatus of the invention, not only can slipping of the corrugated cardboard sheet (10) out of the conveyor belt (20) during advancement or folding be effectively prevented, but also staining of the following sheets can be prevented (10 ) due to the printing ink transferred to the ribbon (20) from the treated sheets, and therefore the number of sheets likely to be discarded as unacceptable articles can be reduced.
