Abstract:
A machine for packaging cigarettes is disclosed. The machine includes a plurality of rotatable translator members - preferably three - each having a plurality of compartments - preferably four - for receiving a group of cigarettes. The translator devices are each rotatable about a respective horizontal axis of rotation, the axes of rotation are mutually spaced apart and the translator members are staggered relative to one another in a direction parallel to their axes of rotation. Thus, next adjacent translator members are so disposed relative to one another that a group of cigarettes from a compartment in one of the translator members, or a group of cigarettes which have been wrapped to form a package as the case may be, can be pushed directly and by a simple sliding motion from a compartment of that translator member to a compartment in a next adjacent translator member while the two compartments are aligned end-to-end in the axial direction. The machine also includes means for feeding an inner wrapper into a compartment in a second translator member, and means for feeding an outer wrapper into a compartment of a final translator member.
Abstract:
A device for folding a sheet of wrapping material around external surfaces of an article of parallelepipedonal shape is disclosed. The device comprises a revolver provided with wall members defining a plurality of cells, the revolver being so rotatable stepwise that each of the cells comes to rest successively at a first station, a second station, a third station and a fourth station of the device. The cells are constructed so to receive at the first station a sheet of wrapping material and so to receive at the second station an article to be wrapped that such sheet of wrapping material is disposed between the received article and walls of the cell in which that article is received, with lobes of the sheet projecting in a direction radial to the axis of rotation beyond a radially outward facing side of the article. Folder means are disposed at the second station, the folder means comprising a folder member rotatably mounted on carrier means reciprocatably displaceable along guide means, and drive means to displace the folder member between a first position - in which the folder member is radially spaced apart from the radially outward facing side of a cell at the second station - and a second position - in which the folder member is disposed next adjacent the radially outward facing side of the cell at the second station. The drive means, in displacing the folder member from its first position towards its second position, initially imparts rotational motion to the folder member relative to the carrier means and, subsequently to the initiation of the rotational motion, imparts such translational motion to the carrier means that - when the device is in use - the folder member is moved along the radially outward facing side of the cell at the second station to engage one of the radially projecting lobes and to fold the latter against that side of an article in the cell.
Abstract:
An apparatus for packing articles, such as cigarettes, cigars or cigarillos, comprising a takeup device for picking up rows of objects and depositing each row in a container with the articles of one row lie in the recesses formed by articles of the row below. The takeup device comprises at least two parts separable from one another to vary the number of objects to be picked up depending on whether the sections are joined together or separated from one another. Further means are provided for delivering a series of the articles over a path so that they may be picked up by the takeup device.
Abstract:
A SPLICING DEVICE COMPRISING PRESSING MEANS, MEANS FOR FEEDING A TRAVELLING WEB AND THE LEADING PORTION OF A STAND-BY WEB BETWEEN THE PRESSING MEANS, MEANS FOR MOVING THE PRESSING MEANS TOWARDS EACH OTHER TO PRESS A PORTION OF THE TRAVELLING WEB AND THE LEADING PORTION OF THE STAND-BY WEB TOGETHER, AND MEANS FOR DISPLACING THE PRESSING MEANS TO TRAVEL JOINTLY ALONG THE PATH OF THE WEBS WHILST PRESSING THE WEBS TOGETHER. ADVANTAGEOUSLY, MEANS ARE PROVIVED FOR PRE-HEATING THE PRESSING MEANS SO THAT WEBS OF THERMOPLASTIC MATERIAL OR HAVING SPLICE PORTIONS WITH A THERMOPLASTIC COATING ARE WELDED.
Abstract:
A milling or grinding machine for shaping a workpiece is disclosed wherein a shaping tool is displaced relative to a rotatable workpiece in accordance with coded displacement values of a series of signals stored on a perforated tape. The signals are extracted from the tape serially and are applied to computer means, which provides further signals each coded to represent a displacement value in predetermined proportionality to the displacement represented by a respective one of the extracted signals. These further signals are translated into command signals, which are applied to a stepping motor for imparting displacement to means supporting the shaping tool. The stored signals are extracted from the tape in response to output pulses derived from a frequency divider network, the input of which is connected to a pulse generator. The pulse generator is so coupled to means for rotating the workpiece as to provide a plurality of pulses for each predetermined angular displacement of the workpiece. The frequency divider network includes a plurality of successively connected frequency divider devices, each of which is manually settable to provide output pulses equal in number to the number of pulses applied to the input of the selected frequency divider device divided by the respective divider ratio to which the selected divider device is set. By adjusting the divider ratios set at the respective divider devices, the angular displacement of the workpiece is correlated with the displacement of the shaping tool in a predetermined manner.
Abstract:
A method of providing a web of packaging material with a tear strip is disclosed. The method comprises the steps of feeding such a web of packaging material along a feed path, perforating the moving web in a zone extending substantially parallel to the longitudinal edges thereof, cutting a strip from a web of tearstrip material, applying the cut strip to one surface of the web of packaging material to overlie the zone of perforation, applying suction to the respective opposite surface of the web of packaging material to retain the cut strip against said one surface, and bonding the cut strip to the web of packaging material. Advantageously, the bonding step comprises the application of heat to weld the cut strip of tear-strip material to the moving web of packaging material. Also disclosed is a device for carrying out the method. The device comprises feeder means to feed such a web of packaging material along a feed path, perforator means to perforate the moving web of packaging material in a zone substantially parallel to the longitudinal axis thereof, cutting means to cut a strip from a web of tearstrip material, applying means to apply the cut strip to one surface of the web of packaging material to overlie the zone of perforation, means for applying suction to the respective other surface of the web of packaging material to retain the cut strip against said one surface, and bonding means to bond the cut strip to the web of packaging material.
Abstract:
A cutter device for cutting continuous webs into lengths is disclosed. Two webs are guided along respective web feed paths which are mutually convergent and have a portion in common with one another. Each web feed path is provided with respective web feeder means and the web feeder means are actuatable alternately. First and second cutter means are disposed in the respective feed paths. Further cutter means is disposed in the web feed path portion common to the respective web feed paths and downstream of the respective first and second cutter means. Each of the first and second cutter means comprises a first member rotatably displaceable relatively to a second member to bring mutually cooperable knife elements of the first and second members into cooperative action. Preferably, each of the first and second cutter means is so mounted that at least one of the first and second members of each of the respective first and second cutter means is displaceable from an inoperative position to an operative position, in which the rotatable displacement causes the cooperative action between the knife elements.
