摘要:
To pack a group of cigarettes in a rigid packet, a collar, a respective inner sheet of wrapping material and a respective group of cigarettes are fed successively into a same conveying seat in which the collar and the inner sheet are at least partly folded together about the group of cigarettes as of respective flat initial configurations.
摘要:
A method and machine for wrapping a product in a sheet of heat-seal wrapping material, whereby the sheet of wrapping material is folded by a fixed folding device onto a wall of the product so as to superimpose at least two portions of the sheet of wrapping material; the sheet of wrapping material, once folded, is gradually released from the fixed folding device; and a sealing surface of a sealing head is brought gradually into a position facing the superimposed portions as the superimposed portions are gradually released from the folding device.
摘要:
A method for gumming sheet material, whereby a sheet is fed along a path directly facing a free surface of a bath of gum, and an electric field is generated over a portion of the sheet to draw the gum onto the portion.
摘要:
A wheel for conveying products, in particular packets of cigarettes, is mounted for rotation about an axis, and presents at least one manipulating unit, the outer casing of which is fitted with a pocket for a packet and with a number of manipulating elements, and houses a control shaft presenting cams for controlling the manipulating elements; the casing is fitted releasably to a frame of the wheel; and the control shaft is connected to a countershaft by a face joint.
摘要:
The filling of a cigarette is controlled by detecting a brightness curve of at least one part of the open end of the cigarette, processing the resulting brightness curve to obtain a contrast index, and comparing the resulting contrast index with an equivalent index of a correctly filled cigarette to obtain a signal indicating acceptance of the cigarette under observation.
摘要:
The filling of a cigarette under observation is controlled by intersecting the open-end surface of the cigarette with at least one coherent light blade emitted by at least one laser source, to form a respective real light trace, and by analyzing any deviation or discontinuity of the real trace in relation to a theoretical, straight, continuous trace formed by joining two end points of the real trace, to obtain a signal indicating acceptance or rejection of the cigarette under observation.
摘要:
A cigarette packing machine for producing a rigid packet a hinged lid has a first packing unit which folds a first blank about a group of cigarettes to form an outer container with a hinged lid; and a second packing unit which folds a second blank about the outer container to form a tubular slide surrounding the outer container to slide axially with respect to the outer container; the tubular slide has a transmission member, in turn having a first end integral with the lid, a second end opposite the first end and integral with the slide, and a deformable intermediate portion having a U-shaped fold between the outer container and the slide.
摘要:
A rigid packet for loose pastilles, sweets or similar items is composed of an outer casing (2), and an inner casing (3) with a small opening (4), accommodated slidably in the outer casing (2). The packet can assume a closed configuration in which the opening (4) is concealed completely by the outer casing (2), or an open configuration in which the opening (4) is at least partly exposed and is furnished with a mechanism (14) designed to lock the inner casing (3) in the closed position; the locking mechanism (14) can be operated from externally of the packet to release the inner casing (3) and allow it to slide toward the open position.
