Abstract:
The device comprises a guide (23) defining a closed for a plurality of separator fingers (15). In the vicinity of the end of the advance stretch of the guide is set a separating member (101) provided with a movement of insertion and extraction (f103) with respect to the pile of products (P, P1, P2), synchronized with the movement of advance of the products along the path of advance, so as to insert itself between two contiguous packs of laminar products (M1, M2), between which is inserted a respective separator finger (15), and to withhold temporarily the pile of laminar products whilst said separator finger (15) is moved away from the path of advance.
Abstract:
The rotating cylinder for processing a web material comprises an essentially rigid cylindrical core (13), on which is fitted an interchangeable sleeve (45) of elastically expandable material whose rigidity is less than that of the material of the core; the sleeve is axially and angularly fixable to the core and is provided on its outer surface with a relief pattern. For each end of the 3 cylinder, there is provided at least one corresponding mechanical locking member which can be fixed to the corresponding end of the core of the cylinder and which interacts with the corresponding end of the interchangeable sleeve to lock the interchangeable sleeve angularly with respect to the core of the cylinder.
Abstract:
A description is given of a device for controlling the discharging of rolls (R) from a rewinder, comprising a rolling surface (11) on which the rolls roll as they leave said rewinder and a member (17) able to rotate about an axis parallel to said rolling surface and perpendicular to the direction of discharge of the rolls. During operation, the rotatable member always rotates in the same direction about its own axis. It is provided with at least two roll retaining surfaces defining, with the rolling surface, a roll containing zone.
Abstract:
A method of making wet rolls includes providing a web of material, applying a wetting solution to the web to produce a wet web, and winding the wet web into a roll. The wetting solution may be applied at an add-on greater than 25%, and the web may travel at a speed of at least 60 meters per minute.
Abstract:
A device for discarding trims formed by cutting machines during the cutting of paper logs, including an advancing plane on which paper rolls (R) and trims (RT, RC) advance along a given direction (A), wherein the trims can fall through a discontinuity provided on the advancing plane. The advancing plane is formed by a first extendible conveyor (1) and a second extendible conveyor (2). Each of the conveyors (1, 2) is connected with an extension and retraction device. The discontinuity on the advancing plane is realized or eliminated depending on the extended or not extended configuration of the conveyors (1, 2).

Abstract:
The device includes at least one continuous flexible suction conveyor which is equipped with openings and which conveys articles along a transfer path from an article feeder to an article received. A discharge point for the trimmings is provided along the transfer path. A suction system is also provided which is associated with the conveyor and which generates a suction through the openings along the transfer path. At least one obturator element, which is movable along the transfer path and which temporarily closes the openings of the conveyor opposite the trimming or trimmings, is provided.
Abstract:
The rewinding machine for the production of rolls of weblike material comprises: a winding-up system (1, 3, 5) for winding up the weblike material on winding-up mandrels (M), and an extractor (23) for separating the mandrels from the respective rolls formed thereon. A device for washing the mandrels is also provided.
