Device to emboss at least two-layer flat articles, for example, toilet paper, handkerchiefs, etc Proposed device comprises at least one first and at least one second pair of rolls thus making embossing roll and rubber roll. First pair embossing rolls comprises multiple uniformly distributed embossing points in amount of 20 to 70 per one cm2 for flat micro embossing on at least one layer. Second pair embossing roll comprises first and second zones distributed over its area. First zone comprises multiple embossing points in amount of 45 to 70 per one cm2 for flat micro embossing on at least one web of the nest layer. Second zones comprise no embossing points and make not over 40% of total embossed area and are not interconnected. Device comprises also at least one paster arranged nearby second pair embossing roll and directly behind rubber roll. Said paster applies glue on roll embossing points. Embossing rolls are arranged to provide a clearance to bring embossed layers together. To produce laminar joint of layers, connecting roll is arranged nearby first pair embossing roll. |

Container, preform, mandrel and method of producing container Invention relates to sheet preforms, container made thereof and method of container fabrication. Sheet preform consists of cellulose material layer and thermoplastic layer. Said preform comprises a number of casing panels consisting of 1st, 2nd, 3rd and 4th panels, and a number of panels that cover the casing face and runs, in fact, parallel about aforesaid casing panels, and consist of 1st, 2nd, 3rd, and 4th panels that cover casing face. Each of 2nd and 4th face covering panels has 1st and 2nd inclined loose line that divide their panels into central subpanel adjacent to appropriate 2nd and 4th casing panels, and two end subpanels. Each of central subpanels features, in fact, triangular shape and runs from casing panel to the apex. First face closing panel comprises central tab extending outward its panel. Central tab is separated from its panel by loose line. The latter is shifted relative to imaginary line running through both apices and is located at the level of the most remote edge of the first face covering panel and imaginary line level. |

Invention refers to drum whereon there is mounted creaser ring in device for creasing material, such as paper. It is the object of the invention to develop a flexible creasing ring which can be split forming two adjacent ends to facilitate installation of a ring into a device without removal of a shaft. Drum (2) for installation of flexible creasing ring (8) of the creasing device is made in form of two parts (14, 15) each equipped with cylinder external surface (12) and an orifice for installation of part of the drum on shaft (4). First and second parts (14, 15) of the drum are of a shape facilitating two parts (14, 15) of the drum abut against each other forming base (18) between them and two side walls of channel (6) for receiving flexible creasing ring (8). At least one side wall of channel (6) has a recess so, that flexible creasing ring (8) positioned in channel (6) and projecting into a side direction into the recess can not be extracted from channel (6) in radial direction. Thus, ring (8) can be installed and maintained in its position without tightening and can be used in the split form. Rings can be replaced in the device without removal of shaft (4) from the machine where it is installed. |
