Problems solved by technology

[0009] Disadvantageously, prior art machines and methods (such as those described above) lack precision and / or are slow to operate to ensure optimal forming thereby preventing the container from opening during one of the subsequent forming operations
[0010] In other words, prior art machines are based on a series of operations which, if not sufficiently coordinated, lead to a non-optimal formation of, or possibly damage to, the container making it unsuitable for containing the aforementioned loose items

Embodiment Construction

[0032] With reference to the drawings, the reference number 1 designates as a whole a machine for forming containers C from blanks S; in the following reference is made to preglued tubular blanks S without loss of generality.

[0033] "Tubular blank" S means such as for example Figure 4A Shown is a blank having a body S1 defining a side wall L, a top opening AS and a bottom opening AI, each opening being provided with a respective end flap A. The term "preglued" denotes a blank that is initially flat and then folded, glued and flattened to define a partially formed blank ready to assume the shape described above. In other words, before entering the machine 1 the flat blank is folded and glued so that when processed its flattened shape will readily adopt a tubular shape with eg a substantially rectangular cross-section.

[0034] exist Figure 4A in (and in Figure 4B ) is shown by way of example with four side walls L and four end flaps A at its top opening AS and four end ...

Abstract

The invention describes a machine (1) and a method for forming containers (C) from blanks (S), comprising a plurality of forming hoppers (2), an endless conveyor defining a feed path (T) and on which the hoppers (2) are mounted in succession, and a plurality of pushing elements (5), the pushing element (5) can be moved so as to follow the respective forming hopper (2) at least along an extension of the feed path (T), and the pushing element (5) has a reciprocating operational movement towards and away from the respective hopper (2) in a direction transverse to, preferably perpendicular to, the feed path (T). The machine (1) further comprises a folding device arranged downstream of the pushing element (5) along the feed path (T) and configured to produce top closures (CT) and / or bottom closures (CF) of the tubular blanks (S), respectively.

Description

technical field [0001] The present invention relates to a machine and method for forming containers from blanks. [0002] These containers are used to pack loose items of small size. For example, these containers can be used in the food industry for packaging loose confectionary products and the like. Generally, these containers are for example shaped in such a way as to have a cross section tapering from the upper part of the container to the bottom part of the container. Background technique [0003] As is known, machines for forming containers are equipped with a conveyor provided with a plurality of pockets adapted to receive blanks, for example tubular blanks, whether flat or pre-folded and partially glued, to The blank is moved along a path through the station where the blank is formed. [0004] In this case, these containers have at least a body defined by four side walls, a top opening (with an upper end flap) and a bottom opening (with a lower end flap). The con...
