Benefits of technology
"The present invention aims to solve the problems with a packaging machine that synchronizes the speed at which the film is supplied and the speed at which the machine revolves. This invention ensures that the machine operates reliably and efficiently in all situations."
Problems solved by technology
However, during the acceleration and deceleration steps, control is not precise enough, meaning that the above-mentioned synchronising means must be supplemented with a mechanical device, for example of the “dandy roller” type—in which a bar, interacting with the film, depending on the moments increases or reduces the quantity of web supplied—constituting a buffer compensating for any instantaneous synchronisation defect found between the web supply speed and the revolving speed of the movable apparatus.
Such a type of control, although operating in a relatively satisfactory way, may not be completely reliable in all operating situations which may occur in practice.
Moreover, from a construction and economical viewpoint, said control may also be complex and expensive.

Embodiment Construction
[0014]In FIG. 1 of the accompanying drawings, the numeral 1 denotes as a whole a machine 1 for packaging products 2 which substantially has: a parallelepiped structure 20 with a portal delimited by four uprights 21 located at the vertices; a horizontal platform 22 inside the uprights 21; and an annular thrust bearing 23 below the platform 22, which supports an operating apparatus 4 that supplies a film 8 of packaging material.
[0015]The horizontal platform 22 is connected in a guide on the uprights 21 substantially at four of its vertices. The platform 22 can move in such a way that it can translate vertically and alternately along the machine 1 structure 20, driven by drive means 37 which are completely conventional and are not strictly part of the present invention, therefore they are not described in detail. During its translating movement, the platform 22 encloses a generic product 2 to be packaged, said product being contained in the space inside the machine, coaxial with the st...

Abstract
A machine for packaging a product (2) in a wrapper forms the wrapper by wrapping with a film (8) of packaging material, supplied in the form of a continuous web from an apparatus (4) for supplying film (8) which can move relative to the product (2) in such a way that it revolves around the product (2) and translates longitudinally relative to the product (2). The machine (1) comprises mechanical means (10, 5, 14) for synchronising the speed at which the film (8) is supplied with the speed at which the apparatus (4) revolves around the product.
Description
TECHNICAL FIELD[0001]The present invention relates to the technical sector of automatic packaging of products and in particular it relates to a wrapping machine in which products are packaged by forming a wrapper consisting of a film of suitable material which, in the form of a continuous web is wrapped around the product in repeated coils until the product is covered.BACKGROUND ART[0002]In the above-mentioned technical sector there are prior art packaging machines in which the wrapper is obtained using an unwinding apparatus which supplies a continuous web of film and which is supported by an apparatus that can move on the fixed structure of the machine, its motion consisting of revolution around the product to be packaged and translation longitudinally relative to the product, movements which are suitably synchronised with each other.[0003]More specifically, the speed at which the film is supplied is synchronised with the apparatus revolving speed around the product by synchronisi...
