Abstract
Disclosed is a device for transporting plastic-container preforms, the device including an endless circulating element having an outer surface and being capable of moving the preforms along a path by rubbing against the preforms, the device including a stationary mounting defining a planar bearing surface for the preforms, the circulating element having a series of brushes which extend projecting from the outer surface, capable of engaging with the preforms in order to move same by rubbing.
Claims20
Method for transporting preforms (2) of containers made of plastic material, with each one having a tubular wall (3) that defines a body (4) and a neck (5) that are separated by a collar (8) that projects radially from the wall (3) by means of a device (1) comprising an endlessly-circulating element (11) that has an outer surface (16) and that carries a series of brushes (19) that extend projecting from the outer surface (16), able to come into contact with the preforms (2) to entrain them by rubbing along a path (T), with this device (1) comprising a pair of rails (31) that are spaced apart from one another, which together define at least one portion of the path (T) of the preforms (2), with these rails (31) having coplanar bearing surfaces (30) for the hanging by their collars (8) of the preforms (2) oriented neck up, this method being wherein the preforms (2) are guided by means of a neck guide (32) that extends perpendicularly to the rails (31) at a distance from them that is greater than or equal to a height of the neck (5) of the preforms (2).
