摘要:
A method and unit for applying a label to an article, whereby a supporting head is fed by a conveyor along a labelling path; the label is fed to a first seat of the supporting head; the article is fed to a second seat of the supporting head; and a relative movement is produced between the first seat and the second seat of the supporting head to apply the label to the article.

Tobacco products are wrapped by a unit equipped with a rotating drum carrying a set of holder mechanisms around the periphery, each rotatable about an axis parallel to the axis of the drum, by which single products are supported and carried through an assembly station together with leaves of wrapping material received from a vacuum roller turning on an axis parallel to the axis of the drum; the vacuum roller revolves tangentially to the drum at the assembly station and comprises a system by which each leaf is transferred to a gripper associated with the support mechanism. The transfer system is timed to operate in a situation of substantially zero relative peripheral velocity between the support mechanism and the vacuum roller.

In a packaging machine, typically a cellophaner for overwrapping packets of cigarettes, each of the packets is enveloped by a wrapping unit in a heat shrinkable wrapper presenting at least two opposite faces disposed parallel one with another. The machine also comprises a unit by which heat is applied to the wrappers, equipped with a pair of belt conveyors that present two branches, facing one another and set in motion in such a way as to transport the packets by gripping the two opposite faces of each wrapper, and at least one heating head associated with each transport branch; the heating heads are faced with a leaf of lamellar graphite bonded to the head on one side and offered in direct contact on the other to the respective branch of the corresponding belt conveyor, so as to minimize friction between the belt and the head.

摘要:
A method of making a brand change, on an automatic production system for processing tobacco articles and which produces a first product from first materials; the method has the steps of: stopping the automatic production system once production of the first product is completed; feeding second materials onto the automatic production system; restarting the automatic production system to commence production of a second product from the second materials; checking all the second products in a first lot to ensure each second product in the first lot conforms with production specifications; externally marking each second product in the first lot conforming with production specifications; and generating a pass signal when a given number of consecutive second products conforming with production specifications is produced.
摘要:
A method and unit for applying labels to products fed by a conveyor along a conveying path; a number of pickup heads are fed along a feed path to withdraw the labels successively from a feeder and apply the labels successively to respective products on the conveyor; and, in the event of stoppage or malfunctioning, the pickup heads are fed along a reject path, adjacent to the feed path, to transfer at least some of the labels on the pickup heads to a collecting device.
摘要:
A label feeder unit associated with a machine for packing tobacco products holds a stack of labels placed in a channel presenting an infeed end, and an outfeed end from which the labels are released to a take-up station, then picked up singly and transferred to a further unit of the machine. The outfeed end of the channel incorporates a transfer mechanism comprising a pair of contrarotating rollers placed on either side of the channel at a distance less than the width of the stack in such a way as to intercept the labels and transfer them to the take-up station, which is movable relative to the outfeed end of the channel under the pressure transmitted to the station by the labels taken up between the rollers. The transfer mechanism forms part of a feedback control loop by which the pressure registering through the labels at the take-up station is kept within prescribed limits.
摘要:
A rigid container for tobacco items, defined by a tubular lateral wall (11) and by at least one end wall (6), and wherein one of the two walls (6, 11) has at least one inwardly concave portion (13; 82; 91; 96; 102; 113), and the other wall has at least one flat portion (8; 114), which mates with the concave portion (13; 82; 91; 96; 102; 113) along a convex outer edge portion (10, 115) of its own, and is formed from a panel (6′; 6′, 6″; 121a, 122a) having a first portion (6′a; 6′a, 6″a; 128) corresponding to the flat portion (8; 114), and a peripheral second portion defined by at least one curved strip (20; 20′, 20″; 127) bounded internally by a curved crease line (19; 19′, 19″; 126) extending along the convex outer edge portion (10; 115); the strip (20, 20′, 20″; 127) being folded squarely, by drawing, to define a convex border (23; 129) extending along the convex outer edge portion (10; 115), and being made integral with an inner surface of the concave portion (13; 82; 91; 96; 102; 113).
摘要:
Packets of prismatic geometry referable to a longitudinal axis, presenting two larger side faces, two smaller flank faces and two end faces, are overwrapped by a method including a step in which each packet, enveloped initially by a tubular wrap projecting beyond the two end faces, is inserted into a holder of a transfer wheel in such a way that two appendages of the tubular wrap projecting at either end from a first flank face of the packet are flattened over the end faces; the appendages are pinned immediately along two lines coinciding substantially with the corner edges of the end face as the packet enters the relative holder, and held stably in position during a subsequent step of transferring the single packets from a feed station to an outfeed conveyor.
