Abstract:
The embossed or printed web material article comprises at least two plies (V1, V2) of tissue paper joined together by gluing and forming at least one multi-ply sheet. The sheet has a principal pattern (D), embossed or printed, in a substantially intermediate position with respect to the surface of the article, and secondary embossed or printed patterns (U, V) of smaller dimensions arranged along the edge lines of the article and interrupted by said edge lines. FIG. 3 schematically shows an axonometric view of the embossing roller (21). The cylindrical surface of which is indicated with 21S. Defined on the surface of the roller are annular i.e. circumferential areas or bands (21C), along which protuberances are arranged to define an embossing pattern, which will be referred to hereunder as circumferential secondary embossing pattern. A longitudinal band (21L) is also represented on the cylindrical surface of the embossing roller. In actual fact, several longitude bands are provided along the circular extension of the roller. As in case of the circumferential bands, protuberances defining an embossing pattern, which will be referred to hereinafter a longitude secondary embossing pattern, are also provided along the longitudinal bands.
Abstract:
Inner wrappers for packets of cigarettes are fashioned from a continuous strip of metal foil paper directed along a feed path internally of a cigarette packer, advancing through an embossing unit by which the metallic surface is textured, then through a rotary cutter such as will divide the material into leaves of specified length. The embossing unit is equipped with an assembly comprising a pair of rollers, also with a stabilizing mechanism that utilizes an aspirating roller to induce a controlled plastic deformation in the strip, canceling out the random deformations induced by the embossing action, and, with each revolution of the cutter, simultaneously advancing a portion of the embossed strip equivalent to the length of one leaf.
Abstract:
An embossing device having a first embossing unit for satin finishing a strip of packing material, and a second embossing unit for impressing graphics on the strip of packing material; the second embossing unit has two embossing rollers, at least one of which only has embossing pins in areas for impressing the graphics.
Abstract:
This invention relates to a process for manufacturing and packaging rolls of tissue paper, wherein at least one sheet of paper is embossed in an embossing unit that includes an engraved embossing cylinder that includes at least a first zone with a first embossing motif and a second zone with a second embossing motif that is different from the first. Rolls are obtained whose sheet is embossed according to the first motif and rolls are produced whose sheet is embossed according to the second motif. With this procedure, packs that contain rolls having different designs are produced in a simple fashion.
Abstract:
A module for a web-processing machine includes a sub-frame to which are mounted an operating roll (such as a die roll), and means urging the operating roll in one direction. The sub-frame can assume a position in which the operating roll is juxtaposed against and parallel with a driven anvil roll, and a further position in which the sub-frame is released, allowing the operating roll to move away from the anvil roll, so that the operating roll can be quickly and easily removed for replacement or maintenance. Preferably, the sub-frame is hingedly connected to the machine for rotation between the above positions.
