Abstract:
A roll paper product having a machine direction, cross machine direction, two machine direction edges, and one or more plies of a fibrous structure having a pattern embossed on the surface thereof wherein the embossing pattern has a plurality of embossments having a height, one or more first tracts having a cross machine direction width, and one or more second tracts having a cross machine direction width, wherein the first tract has the lower percent unembossed than the second tract; and wherein the roll paper product has been cut such that at least one machine direction edge is tangential to a first tract.
Abstract:
Apparatus for fabricating discrete segments of cushioned web material for use as dunnage. The apparatus includes a mobile supply cart having at least one substantially horizontal support arm for receiving the hollow core of rolled web material. The apparatus also includes a separate driven rugation device with feed rollers for directing multiple plies of the web material in overlying, contacting relationship along a single path of travel. The separate cart and rugation device may be removably interconnected for lateral alignment. Driven interdigitized texturing rolls downstream of the feed rollers emboss a raised pattern on the web material, and a plurality of separating rollers downstream from the texturing rolls separate the plies of web material and direct them in divergent paths of travel. Combining rolls recombine the plies of textured web material such that the embossed areas of each ply do not directly overlie each other but are offset, creating void areas between the adjacent plies. A driven cutter downstream of the combining rolls severs the recombined offset embossed plies into discrete segments. The cutter may have a rotating disc blade with a peripheral edge which moves transverse to the longitudinal length of the plies to cut the plies. Last, driven exit rollers convey the cut segments of material from the rugation device.
Abstract:
Disclosed is a continuous web material wound in a roll (R), with two longitudinal edges (1) and a plurality of transverse perforation lines (3), which divide the web material into detachable sheets (F). The product also has at least one intermediate longitudinal line (5) to facilitate folding or weakening line, between the two longitudinal edges.
Abstract:
The embossed or printed web material article comprises at least two plies ( Vl, 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 alongitude secondary embossing pattern, are also provided along the longitudinal bands.
Abstract:
The invention concerns a multilayered web-like tissue product comprising at least two webs, the layers of this product being held together by an embossed connecting portion common to the layers. The individual layers are smooth or provided with an embossed pattern extending substantially over the entire surface. The invention is characterized in that the embossed connecting portion takes the form of embossed strips (4, 5) which immediately adjoin the edges (2, 3) of the multilayered web (1) on both sides and accommodate part of the web width (6). The invention also concerns a process and a device for producing the above-mentioned multilayered web-like tissue product, a plurality, e.g. two or three, of paper webs (18, 19, 20), which are provided with an embossed nub pattern and whose width is a multiple of the width of the paper web (1) to be produced, being guided together through an axially divided embossing gap which is formed between at least three steel nub-embossing rollers (26), arranged at a spacing from and axially aligned with one another, and one or a plurality of counter-rollers (27) which are associated with these nub-embossing rollers and have a surface preferably of steel, rubber, paper or plastics. After the layers have been joined together in the embossing gap, the resultant multilayered paper web is divided by cuts into a plurality of narrower paper webs, these cuts each being made approximately in the centre of the stripe-like embossed patterns produced when the layers are joined. The process of cutting into a plurality of narrower paper webs, of the width appropriate for the subsequent use of the tissue product, is performed when the paper web has passed through the embossing gap and has been rolled up after the joining process.
