Abstract: The apparatus is formed of two identical devices (A, A′) installed mirror image-fashion, each of which is equipped with a pressure bar (19, 19′) fitted to overhang the relevant lateral toothed conveyor belts (T T′) which move and recircle the said bars, and which are in their turn activated by relevant motors (8, 8′) with electronic speed and phase control governed by one programmable processing unit (26). When the length of the products (P) is less than the length of the straight branches of the conveyors moving the said bars, the two devices are installed mirror-image fashion, with the axles of the pulleys of one conveyor aligned with those of the corresponding pulleys of the other conveyor. In this position, the bars (19, 19′) of the two devices alternate in taking, moving foward by pushing and the final placing of the products in the workstation (K).

Abstract: The thrust bars (11), which are placed behind the product in the transfer phase from one transport line (L1) to one downstream (L2), have an adjustable stop (12) resting against the right side of the direction of travel of this product. By means of ball joints or articulated joints (10, 10′), the ends of the aforesaid bars are connected to the same points of the upper branch or the lower one of a parallel pair of toothed belt conveyors (T, T′) fed on pulleys with horizontal axles, placed inclined at the right angle and bridging the area following the two transport lines and which with their own branch, e.g. with a lower branch, work in the direction running from the upstream line to the downstream line at an identical speed such as to be able to effect, with the above-mentioned bars, the conveyance transfer of products from one to the other conveyor belt by rear and side thrust.

Abstract: A machine for packing groups of rolls of domestic paper in respective sheets of packing material has folding members, each of which has an active portion, which is brought into contact with a flap of a sheet of packing material, and an adjusting device for adjusting the extension of the active portion in a first direction.

Abstract: Rolls of paper are overturned by a device composed of a first conveyor belt interposed between and occupying the same plane as a feed station and a wrapping station, and running at a velocity comparable to the velocity of the feed station, also a flexibly resilient belt disposed facing the first belt, looped over a pair of wheels of which one is power driven; the resilient belt is positioned with one end adjacent to the feed station, separated from the first belt by a distance equivalent to the diameter of the single roll when disposed with its axis parallel to the first belt, and set in motion at a velocity of which the horizontal component is greater than the velocity of the first belt in such a way that the roll will be taken up, rotated through a right angle and positioned with the axis perpendicular to the first belt.

Abstract: In a machine for packaging rolls of household paper products, packs are restrained between groups of vertical teeth associated with a conveyor passing through a wrapping station, a folding station and a heat seal station; equipping the wrapping station with additional vertical teeth fixed to a support afforded by the machine which are positioned alongside and offset from the group of conveyor teeth remote from the folding station, at a distance from the remaining group of conveyor teeth less than the distance which separates the two groups of conveyor teeth, a tighter restraint can be applied as the rolls are enveloped initially in the relative sheet of wrapping film, whereupon the movement of the conveyor teeth beyond the station will allow the sheet to slacken, and the rolls to regain their normal shape.

Abstract: Reams of paper advancing in a horizontal direction on a first belt are straightened initially by interaction with a transverse vertical barrier, while wrapping paper is drawn out from below the first belt and directed onto a third belt; the paper is pulled upright into the path of the ream by the elevation of a first gate affording a gap of height at least equal to that of the ream whereupon the ream is directed through the gap, becoming partially enveloped by the paper, then stopped on the third belt while the wrapping paper is cut near to the gate and the trailing edge simultaneously moistened with gum. Finally a second gate identical to the first is raised at the entry to the third belt, drawing up the remaining portion of the paper, and the conveying direction is reversed to take the ream back through the relative gap; the ream is thus enveloped completely and the gummed edge of the wrapping paper flattened and secured.

Abstract: Rolls of paper are stacked in layers without any relative movement occurring between the surfaces brought into contact, using a transfer table which pivots about a horizontal axis, such that the end directed toward the wrapping machine can be swung vertically into different positions corresponding in number with the number of layers to be wrapped and matched in height with a set of tiered stacking tables, the lowest of which is also the longest; with each stacking table occupied by one layer of the paper rolls, the several layers move forward as one, in vertical alignment, to the point where the top layers run off the ends of the shorter tables together and each roll settles plumb on the roll beneath.

Abstract: An apparatus includes pincers, or suckers, that tension each marker at an angle to the stack of sheets from which it emerges, and a separator mechanism; the separator incorporates a follower with a tapered leading edge that is offered to the taut marker, and a support, to which the follower is hinged, that can be moved from a retracted position to an extended position in which the follower penetrates the stack of sheets, sliding in between the marker and the ream sitting on and separated by the marker.

Abstract: The apparatus includes a suspended locating element against which the stack of sheets is urged and compacted, and a separator mechanism, set apart from the locating element at a distance matching the depth of a compacted ream, the sharp edge of which approaches and penetrates the stack; the separator mechanism is mounted by way of a damper to a drive system that traverses the entire assembly toward the infeed station of the wrapping machine while the remainder of the stack is held and compacted by a separately anchored mechanism to avoid the topmost sheets being dragged along with the separated ream.

Abstract: A feed apparatus for strip wrapping material, comprising two pairs of power driven, breasted belts which incorporate sets of transverse teeth offset one from the other and are looped around respective pulleys driven from the output shaft of a motor interlocked to monitoring and control means; the drive is stopped for a given interval each time the belts are indexed through a distance corresponding to the length of the wrapping sheet, thus ensuring that the sheet lies directly in the path of the oncoming commodity.

Abstract: In a device according to the invention, a roll of narrow strip is unwound, fed through a cutting station and severed into discrete lengths which are conveyed forward above the level of the running sheet of wrapping film and at right angles to the direction in which it is run through the machine. The two ends of each discrete strip are picked up by suckers fitted to the projecting ends of a pair of arms which are drawn together through 90.degree., rotating about respective vertical axes, and thus cause the strip to assume a `U` shape before being attached to the wrapping film in such a way as to furnish a carrying handle.

Abstract: In a device according to the invention, a roll of relatively narrow strip is unwound, measured into discrete lengths in which two C-shaped incisions are punched, then indexed through a cutting station and conveyed forward singly above the level of the sheet of wrapping film, at right angles to the direction in which it is run through the machine. The two ends of each discrete strip are picked up by suckers that draw together through a plane parallel with the path through which the strip is conveyed, while the strip itself is lifted from the middle; the strip is thus made to assume an upturned `T` profile, with the two incisions sandwiched together, before being offered and heat-sealed to the sheet film from which single wrappings are ultimately formed.
