Title (EN) MACHINE FOR PRODUCING THE BODIES OF CONICAL RECEPTACLES
(FR) MACHINE DE PRODUCTION DES CORPS DE RECEPTACLES CONIQUES
Abstract: front page image
(EN)A machine for producing the bodies (74) of conical receptacles (73) having an inner annular bottom shoulder (75). The receptacles are intended to be made from pasteboard and cardboard waste material in the form of narrow, strip-like webs. The machine comprises the following main parts: a rotatably driven shaping member (5) having a conical jacket face (6), a support frame (61) holding a web (24) of material in the form of a narrow strip wound into a roll (62), which web is intended to be used to form the conical bodies (74) of the receptacles (73) by being wound about the shaping member (5), a device adapted to releasably secure the starting end (23) of the web (24) of material to the smaller end of the shaping member (5), and a device (2, 3) to effect axial displacement of the shaping member (5) relative to the support frame (61) during the rotation of the shaping member (5) for the purpose of winding of the web (24) of material in helical winding turns around the conical jacket face of the shaping member while ensuring that the discrete winding turns (81) only partly overlap in this area and adhere to each other by means of an adhesive. The invention is characterized in that at its smaller end (12), the shaping member (5) is provided with a cylindrical portion (13) the diameter of which is slightly smaller than the smallest diameter of the conical jacket face (6) of the shaping member (5), that a guide lid (17) is arranged to be moved towards the smaller end (12) of the shaping member (5) so as to cover said end for the purpose of guiding the web (24) of material, while the latter is being wound onto the shaping member (5), that a pair of clamping jaws are arranged at the smaller end (12) of the shaping member (21, 22), one of the jaws (21) being stationary while the other one (22) is arranged for displacement towards and away from the stationary jaw (21) to clamp the starting end (23) of the web (24) of material to the shaping m ember (5), and that a slit (39) is provided in the cylindrical portion (13) of the smaller end (12) of the shaping member (5), which slit (39) is open towards the smaller end (12) of the shaping member (5) so as to allow reception therein of the starting end (23) of the web (24).
(FR)Machine de production des corps (74) de receptacles coniques (73) ayant un epaulement de fond annulaire (75). Les receptacles sont fabriques a partir de pattes et de carton de rebut sous forme de bandes etroites en forme de languette. La machine comprend les pieces principales suivantes: un organe de faconnage entraine en rotation (5) ayant une chemise a face conique (6), un bati de support (61) tenant une feuille (24) de materiau sous forme d"une bande etroite enroulee dans un rouleau (62), laquelle feuille est destinee a former les corps coniques (74) des receptacles (73) par enroulement autour de l"organe de faconnage (5), un dispositif adapte pour fixer de maniere liberable l"extremite initiale (23) de la feuille (24) de materiau vers l"extremite la plus petite de l"organe de faconnage (5), et un dispositif (2, 3) pour effectuer le deplacement axial de l"organe de faconnage (5) par rapport a la structure de support (61) pendant la rotation de l"organe de faconnage (5) dans le but d"enrouler la feuille (24) de materiau suivant des spires d"enroulement autour de la chemise a face conique de l"organe de faconnage tout en s"assurant que les spires d"enroulement (81) ne se chevauchent que partiellement dans cette region et adherent les unes aux autres a l"aide d"un adhesif. Une caracteristique de l"appareil consiste en ce que, a son extremite la plus petite (12), l"organe de faconnage (5) est pourvu d"une portion cylindrique (13) dont le diametre est legerement plus petit que le plus petit diametre de la chemise a face conique (6) de l"organe de faconnage (5), et en ce qu"un couvercle de guidage (17) est dispose pour etre deplace vers l"extremite la plus petite (12) de l"organe de faconnage (5) de maniere a recouvrir ladite extremite dans le but de guider la feuille (24) de materiau pendant que cette derniere est en cours d"enroulement sur l"organe de faconnage (5); l"appareil se caracterise egalement en ce qu"une paire de machoires de fixation (21, 22) est disposee a l"extremite la plus petite (12) de l"organe de faconnage, l"une des machoires (21) etant stationnaire tandis que l"autre (22) peut se deplacer vers et en retrait de la machoire stationnaire (21) pour fixer l"extremite de depart (23) de la feuille de materiau (24) sur l"organe de faconnage (5), et en ce qu"une fente (39) est prevue dans la partie cylindrique (13) de l"extremite la plus petite (12) de l"organe de faconnage (5), cette fente (39) etant ouverte vers l"extremite la plus petite (12) de l"organe de faconnage (5) de maniere a pouvoir recevoir a l"interieur l"extremite de depart (23) de la feuille (24).
