A method and apparatus for wrapping a folio ream. The method comprises pre-creasing a wrap sheet and driving the ream into the wrap sheet toward a fold position. A bubble of wrap is formed in the wrap sheet, which is cut while the ream advances, such that a lower flap of the wrap sheet extends beyond the rear edge of the ream. An upper flap fold is formed on the rear edge of the ream, and glue is applied to the lower flap as it is held flat via a vacuum. The lower flap of the wrap sheet is then folded in an upward direction, while the vacuum simultaneously applies a force to an opposite side of the lower flap to keep it flat during folding. The ream is reversed to compress the glue between the lower and upper flaps, forming a rear edge seam on the folio ream.

The apparatus is formed of two identical devices (A, A') installed mirror image-fashion, each of which is equipped with a pressure bar (&#x2032;) fitted to overhang the relevant lateral toothed conveyor belts (T, T&#x2032;) which move and recircle the sai bars, and which are in their turn activated by relevant motors (&#x2032;) with electronic speed and phase control governed by one programmable processing unit (). 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 (&#x2032;) of the two devices alternate in taking, moving foward by pushing and the final placing of the product in the workstation (K). However, when the length of the products exceeds the length of the said conveyors moving the bars, the possibility is offered of acting on both means, allowing anticipation of the longitudinal position of one device in relation to the other, so that the products are firstly taken by the bar (&#x2032;) of device (A&#x2032;) working in advance and are transferred from it in phase to the bar () of the downstream device (A), which in turn provides for the transfer and phased placing of the product in the workstation (K).

The thrust bars (), which are placed behind the product in the transfer phase from a first transport line (L) to a downstream line (L), have an adjustable stop () resting against the one side of the product in the direction of travel of this product. Articulated joints ('), connect the ends of the bars to corresponding points of the upper branch or the lower branch of a parallel pair of toothed belt conveyors (T, T&#x2032;) fed on pulleys with horizontal axles, which are inclined at a right angle to the conveyors (T,T&#x2032;) which bridge the area between the two transport lines and which with their one branch, work in the direction running from the upstream line to the downstream line at an identical speed to each other such as to be able to effect, with the above-mentioned bars, the transfer of products from one conveyor belt to the other by rear and side thrust. Guides (&#x2032;) are provided parallel to the conveyor (T) connected to the outer edge of the junction area of the conveyor lines to guide the right-hand edge of the product in the working direction during the transfer phase, particularly when this product is very long.

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.

Overturning device in machinery for wrapping groups of commodities

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.
