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:
A blade of a cutting tool is stuck into a medium adhered on a support member and is stopped in a state in which a blade edge is positioned between upper and lower surfaces of the medium. A cut line is formed in the medium by the support member and the cutting tool being moved. The blade is pulled out from the medium. An embossing tool is pressed against a position along the cut line of the medium. A continuous recess extending along the cut line is formed in the medium by the support member and the embossing tool being moved.
Abstract:
An arrangement for transforming a planar support (2) includes first and second rotating cylindrical transformation tools (16, 17), cooperating to convert the support (2), first and second side bearings (26, 27), holding the first tool (16) for rotation (Rs), third and fourth side bearings (29, 31), holding the second tool (17) for rotation (Ri), spacers (43, 44, 46, 47) having an inclined face (48) and slidable (S) to adjust the respective distances (e, e1, e2) between the first and third bearings (26, 29) and between the second and fourth bearings (27, 31), to set a radial gap (20) between the two tools (16, 17). In another solution, either as an alternative to or in cooperation with the first solution, the spacer (43) is moved (S) by a differential screw (57) having a first thread (58) that engages with a tapped hole (59) in an integral part (61) of one of the bearings (29) and a second thread (62) different than the first thread (58) and engaging with a tapped hole (63) in the spacer (43).
Abstract:
An embossing device comprises a first embossing roller and a second embossing roller forming a passage for a web of wrapping material to be embossed, which has a main line of extension and a direction of feed; the first embossing roller comprises on its outer surface toothings to make an imprint on the web; a first toothing having a first impression to imprint on said web a first segment of a reference for identifying a section of the web and a second toothing to imprint a decorative pattern on the web; the second toothing comprises a zone without teeth for defining on the web a second, unembossed segment of the reference; the first toothing and the zone without teeth are offset from each other along a directrix of the first roller.
Abstract:
Method of manufacturing a hygiene paper product in form of a continuous paper web (W) of sheets partly separated by perforation lines (9) and wound to a log of predetermined longitudinal length, providing a continuous paper web (W), moving the continuous paper web in a direction of its longitudinal extension, providing at least one embossed pattern on the continuous paper web, providing in the area of an embossing station at least one mark (6, 7) onto the continuous paper web, which mark (6, 7) is in register to the embossed pattern, sensing the mark and controlling perforating means for registering the perforation lines (9) with the embossed pattern thereby imparting perforation lines to the continuous paper web in predetermined longitudinal distances, winding up the resulting web to logs, and cutting the log into rolls.
Abstract:
Method and apparatus for manufacturing a hygiene paper product includes: providing a continuous paper web, moving the continuous web in the direction of its longitudinal extension, applying a repetitive creative structure relative to the longitudinal extension of the web as a first pattern to the web with a first roll, applying a repetitive functional structure relative to the longitudinal extension of the web as a second pattern to the web with a second roll, while enabling the first pattern to be in register with the second pattern by concurrently controlling the repetitive surface speed of continuous web and the phasing between the first roll and the second roll.
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.
