The disclosure relates an apparatus and method for assembling at least two webs of tissue paper with or without marking of the webs. The apparatus and method utilize a multi-marrying roller configuration, which allows for assembling of the at least two webs of tissue paper by passing between the marrying roller and the second marrying roller. The apparatus and method make it possible to produce a conventional embossed product, or a smooth product without marking, having combined plies. In addition, the apparatus and method make it possible to easily move from one production mode to the other.

Installation for assembling two webs of tissue paper with or without marking of said webs

The invention relates to a coreless roll including of a sheet made of dry flexible material, such as an absorbent fibrous material, that is formed by the rolling of a sheet around a winding axis characterized in that it includes a center-feed (center unwinding) first strip forming a projection along the axis in relation to at least one part of the plane of one of the sides of the roll. In particular, this first strip is constituted by a portion of the internal end of the sheet constituting the roll. The first internal turn is thus permitted to unwind, even if the center opening is reduced.

Centre-feed roll and production methods thereof

This invention relates to a method for the production of a coreless roll (') including a sheet () of flexible, not moist, material such as a fibrous absorbent material, produced by winding of the sheet in one direction and rolling this sheet about a winding axis perpendicular to such direction, and including a central dispensing leader forming a projection along such axis relative to at least one part of the plane of one of the sides of the roll. The method is characterized in that the leader is produced by displacing a portion of the end of the sheet () before winding so that one of the longitudinal edges of the sheet forms an angle (&#x3b1;) other than zero relative to such direction of winding, after which winding of the sheet about the axis is initiated. By preference several sheets are produced by longitudinal cutting of a wide sheet. The solution may be applied for production in particular of general wipe rolls, hand towel rolls, or toilet paper rolls.

Method for making a central unwinding roll and resulting roll

The invention relates to a flexible packaging of parallelepipedal form for flexible, superposed flat elements, which may or may not be interlinked, forming a stack of axis XX, comprising a breakable zone () capable of constituting a dispensing opening that is initially closed and delimited by a line of weakening (), said zone () extending over three faces () of the packaging. The breakable zone () is circular, or substantially circular, of diameter D, the greater part of the zone () is centred on one () of the faces of the packaging perpendicular to the stacking axis XX, and the other two parts of the breakable zone () being arranged on two faces () of the packaging that are parallel to the axis XX of the stack.
