Abstract:
The severing machine comprises, in combination: a series of cutting blades (23) rotating about respective axes; a feeder (111) rotating about an axis (111A) approximately parallel to the axis of the disk-shaped blades, having at least one peripheral seating (115A, 115B, 115C) for the products (L): a flexible member (201) passed around at least one portion of the periphery of the rotating feeder, in order to retain the products in the respective seating during cutting (FIG. 1).
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).

The said advancing plane is formed by a first extendible conveyor (1) and a second extendible conveyor (2). Each of said conveyors (1, 2) is connected with extension and retraction means. The said discontinuity on the advancing plane is realized or eliminated depending on the extended or not extended configuration of said 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.
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 include an inorganic salt and at least one preservative.
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 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 include an inorganic salt and at least one preservative. The wetting solution may be distributed evenly throughout the wet roll.
Abstract:
The device for removing front and end trimmings in a series of aligned rolls comprises: at least one continuous flexible suction conveyor (13); a suction system (3) associated with the conveyor so as to generate a suction through openings (13A) in the conveyor; a device for eliminating trimmings along a roll transfer path; a device receiving rolls from the conveyor. The receiver comprises at least two alternate paths for the rolls, which are arranged in sequence along the conveyor (13) and onto which the rolls may be alternately sorted.
Abstract:
The severing machine comprises at least a first series of disk-shaped blades (23A; 23B) rotating about their own axis, which series is carried by a moveable support (21) capable of bringing the series of blades alternately into an active zone wherein the cutting of the products takes place and a parking zone. In addition, at least one barrier (41, 43) is provided separating the active zone from the parking zone.
