The rotating cylinder comprises: an elongated inner core () which is substantially rigid and an interchangeable sleeve () which is fitted onto the core; the sleeve is axially and angularly constrained to said core and is provided on its external surface with a raised pattern. The internal surface of the interchangeable sleeve and the external surface of the inner core are conical surfaces which are mutually complementary; axial and angular locking of the interchangeable sleeve and the inner core is achieved by the friction between the conical surfaces which are forced axially one onto the other.

Method of manufacturing cylinder with interchangeable sleeve

The rotating cylinder for processing a web material comprises an essentially rigid cylindrical core (), on which is fitted an interchangeable sleeve () 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.

A description is given of a device for controlling the discharging of rolls (R) from a rewinder, comprising a rolling surface () on which the rolls roll as they leave said rewinder and a member () 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.

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.

Wet roll having uniform composition distribution

The device comprises a guide () defining a closed for a plurality of separator fingers (). In the vicinity of the end of the advance stretch of the guide is set a separating member () provided with a movement of insertion and extraction (f) with respect to the pile of products (P, P, P), 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 (M, M), between which is inserted a respective separator finger (), and to withhold temporarily the pile of laminar products whilst said separator finger () is moved away from the path of advance.

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.

Device and method for eliminating front and end trimmings from series of rolls

The device for removing front and end trimmings in a series of aligned rolls comprises: at least one continuous flexible suction conveyor (); a suction system () associated with the conveyor so as to generate a suction through openings (A) 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 () and onto which the rolls may be alternately sorted.

Device for eliminating the front and end trimmings from series of rolls and for sorting the rolls

The accumulator () comprises at least two continuous flexible members () equipped with supports () for the products (A). The supports () project laterally with respect to the respective flexible member; each flexible member and at least one first guide wheel (A) being arranged so that the supports face the axis of the wheel in the section of flexible member trained about said guide wheel. The guide wheel is equipped with a plurality of radial arms between which a space is provided for the elongated products resting on said supports. The position of the supports is timed with respect to the position of the radial arms.

Accumulator for elongated products, such as tubes and the like

The severing machine comprises, in combination: a series of cutting blades ( ) rotating about respective axes; a feeder ( ) rotating about an axis ( A) approximately parallel to the axis of the disk-shaped blades, having at least one peripheral seating ( A, B, C) for the products (L): a flexible member ( ) 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. ).
