    DESCRIPTION
    Conformation duct
    The present invention relates to forming machines for packaging machines.
    BACKGROUND
    U.S. patent application 13/421596, filed on March 15, 2012, discloses a shaper for a packaging machine.
    The shapers are used to receive the bag-shaped bag material and reconfigure the band in tubular bag material to be supplied to a packaging machine. The product is supplied to the inside of the tube, then forming the packaging machine transverse closures and transversely cutting the bag material to form product bags. As a concrete example, the product can be a snack food such as chips.
    A forming assembly includes a mounting plate on which a metal sheet is fixed that provides the forming surface on which the band of bag material passes to be reconfigured in a tubular configuration. The surface of the shaper converges upwards to an upper opening through which a tubular product emerges, in which the product is supplied inside the bag material. A forming duct (tube) is arranged above the former.
    Above the forming duct is a scale that supplies batches of product to the tube to be supplied inside the tubular bag material. The scale includes a plurality of baskets angularly spaced around a generally vertical axis. The baskets are open to supply the desired amount of product to form a batch to be placed in a bag to be formed. As the lots move down, the lots get longer. This lengthening of the batches results in the packaging machine located below operating at a reduced speed. Another drawback is that when batches that move downward are further slowed down, aggravating the inconvenience of batch lengthening.
    The disadvantages of the aforementioned sets are that they produce a lengthening of the lots and reduce the speed of the lot.
    OBJECTIVE
    The objective of the present invention is to avoid or substantially improve the above drawback. CHARACTERISTICS OF THE INVENTION
    In this report a forming set for a packaging machine is disclosed, including the set:

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
    In the attached drawings, a forming assembly -10- for a packaging machine, such as that described in U.S. Pat. 5622032, 7159376 and 4753336. In U.S. Patent Application 13/421596 a forming assembly is particularly described, of which the preferred embodiment described below is an improvement.
    The forming assembly -10- includes a frame -11- comprising a first element -12- of the frame having a "U-shaped" configuration, so that it has a base -13- from which diverging arms extend -14-. The element -12- of the frame is of tubular construction, such that it has a longitudinally extending passage in which a gas can be supplied.
    The frame -11- also includes transverse support elements -16- fixed to the end parts -15- of the arms -14-, the element -16- extending inwards with respect to the central vertical axis -19-.
    Supported by the frame -11- is a forming support -17- (shown in "hidden lines") that has a shaping surface -18- over which the material band -32- passes for bags to be shaped with a tubular configuration -23-. The surface -18- is oriented outwards away from the axis -19- and generally surrounds the axis -19-, converging upwards towards the axis -19- to form the opening -20- of the shaper through which pass the axis -19-. Extending towards the opening -20- is the tubular duct -21- of the product supply which has an interior -22- in which the product is delivered for delivery to the inside of the tubular material -23- for bags, of which formed product bags,
    The opening -20- is located adjacent to the lower end of the duct -21- so that the bag material that engages and moves upwardly on the surface -18-, can be redirected down through the opening - 20- to then extend in the direction -34- towards the packaging machine below.
    The surface -18- extends upwards and ends at the opening -20- with a rib -35- adjacent to the opening -20-. The nerve -35- has the shape of an arc edge. A tubular part -24- of the shaper -17- extends downward from the nerve -35-. The tubular material -23- for bags slides down inside the tubular part -24- of the forming support -17- to be supplied to the packaging machine located below. The part -24- can be partially or completely tubular in configuration.

    The forming support -17- is supported by the elements -16- being fixed to the tubular part -24- of the forming support -17-.
    The frame -11- further includes a central assembly -25- fixed to the base -13- so that it extends upwardly therefrom. Attached to the assembly -25- is a support -26- that extends vertically fixed at its upper end to the product supply duct -21- to support the duct -21-. The conduit -21- can also be fixed to the assembly -25- so that it is additionally supported therein.
    The shaper -17- has a transverse peripheral length -31- that is folded, so that it helps increase the stiffness of the shaping support -17-. This transverse length -31- is fixed to a transverse element -27- fixed to the end parts -15-. A roller -28- is located adjacent but distanced from the transverse part -26- to help supply the sheet of material -32- for bags to the surface -18-. The forming support -17- is therefore supported by the arms -14-.
    One or both of the arms -15- are provided with a coupling -29- through which a gas can be supplied inside the element -12-. As the element 12- is of tubular construction, the gas can be supplied to the mounting part -25- from where it is supplied to a reinforcing element -30- (extending from the tubular part -24-) to supply the gas inside the tubular bag material. If necessary, the element -26- could also be tubular for the supply of gas into the product supply duct -21-.
    The tubular part -24- has a recess -33- that provides access to the film when said film is initially fed to the tubular part -24-.
    The conduit -21- includes a body -40- that surrounds the longitudinal central axis -19-, generally vertical. The body -40- is preferably formed of metal foil and has an inner surface -41- surrounding the axis -19-. Preferably the body -40- has a conical trunk configuration so that it converges downwardly from the upper flange -42- to the lower flange -43-. Consequently, the body -40- is circular in cross-section. The bottom flange -43- is adjacent to the opening -20-. However, it will be understood that the flange -43- ends above the opening -20-, so that it leaves a gap through which the material -32- of the bag can pass to be placed inside the tubular part -24- after passing over the flange -35-.
    As mentioned above, preferably the body -40- is of a truncated-conical configuration. Consequently, it is preferred that the surface -41- converge downwards to the flange -43- with respect to the axis -19-.
    Fixed or formed in an integrated manner with the body -41- there are a plurality of projections -44-. The protrusions -44- are very preferably ribs -45-.
    The projections -44- are located at positions angularly spaced around the axis -19- and preferably have their main direction of extension generally parallel to the axis -19-.
    Very preferably, the projections -44- are ribs -45- as described above, in which case the ribs have the main direction of extension generally parallel to the axes -19- but also extend inward radially in relation to to the axis -19-, so that they have a secondary direction of extension that is radial with respect to the axis -19-. Most preferably, the ribs -45- have no angular direction of extension around the axis -19-.
    The preferred embodiment described above has the advantage of reducing the angular displacement of the product batches around the axis -19-. This is achieved by attaching the product batches to the projections -45- to inhibit their angular displacement around the axis -19-. By inhibiting the displacement of the lots 10 around the axis -19- the elongation of the lot is reduced while the speed of the lots is improved since less energy is lost in rotational energy.
