Multi-functional coilable thin-walled structures are comprised of at least one longeron that is capable of rolling and collapsing upon itself. In some embodiments, the coilable thin-walled longeron is a flange longeron. The flange longeron contains at least two major regions: a web and a plurality of flanges. The web region comprises portions of flanges that are bonded to one another. The plurality of flanges separate from one another on the same end of the web region. The plurality of flanges are similar in thickness and shape.

A line is disclosed for producing logs of web material provided with a system for controlling, in real time, one or more parameters of the logs produced by the line and for facilitating any corrective actions. The line includes a rewinder, a feed path for the logs from the rewinder towards at least one station arranged downstream of the rewinder; and a measurement station. The measurement station includes at least a measurement device for measuring at least one parameter of logs randomly selected from the feed path and held in the measurement station, for example a device for measuring the firmness of the logs. The measurement station further includes first transferring members for transferring selected logs from the feed path to the measurement station, and second transferring members for transferring selected logs from the measurement station to the feed path.

A method for producing coreless roll paper includes a winding step in which paper 11 is wound on a shaft 20 in a roll shape, and an extracting step in which the shaft 20 is extracted from roll paper 12 to form a center hole 13. The shaft 20 includes a body part 22 having grooves 23, and a sleeve 30 is put on and fixed to the body part 22. In the winding step, the paper 11 is wound on the sleeve 30.

A roll body taking-out unit that takes out a roll body from a reel that holds a carrier tape storing components in a state of the roll body and stores the roll body in a case is provided. The roll body taking-out unit includes a separation unit that separates the roll body from the reel, and a roll body storage unit that stores the roll body separated from the reel by the separation unit in a case. Further, the roll body storage unit includes a case holding part that holds an empty case, and a chute part that stores the roll body separated from the reel by the separation unit one by one in the empty case held by the case holding part.

Process for the production of paper rolls, including a step of producing logs (L) of paper material by winding a predetermined amount of paper web (W) about a tubular core (C) oriented transversely with respect to a direction (PP) of entering of the paper web (W) in a rewinder (R) in which the winding is executed, and a step of transverse cutting of the logs (L) to obtain rolls (R) of predetermined length. The cores (C) are produced by a tube-forming machine (T) whose position is intercepted by the direction (PP) of the paper (W) entering the rewinder®.

Equipment for removing paper from parent reels used for the production of paper logs of paper material, including a support system adapted to support an exhausted parent reel, where the exhausted parent reel includes a tubular core on which residual paper to be removed is wound, and including removal capabilities for removing the residual paper from the core when the exhausted parent reel is placed on the support system. The removal capabilities include a suction cylinder having a horizontal axis onto which the paper is transferred by effect of the contact between the suction cylinder and the exhausted parent reel and by effect of the rotation of the suction cylinder around the horizontal axis.

A converting line includes a rewinding machine for winding web material into a log. For time points during a time period of the log wind cycle, predictive information representative of a log to be wound is generated and stored in a memory of a control of the rewinding machine. An image capture device is enabled to capture a plurality of images of the log being wound in the winding nest at the plurality of corresponding time points during the time period. Log image capture information is generated based upon the plurality of captured images and corresponding time points during the time period. The log image capture information is compared with the generated predictive log image information to determine a difference in log image. Revised predictive log image information is generated based at least in part upon a difference in the log image capture information relative to predictive log image information.

The present invention relates to a holding system for holding sheet material for plotters characterized in that it comprises at least one substantially tubular side holding element (1), at least part of the external surface (2) thereof being tapered. Furthermore, said side holding element (1) comprises a longitudinal opening (7) and has internal chamfers at one of its ends (4). As a result of the thickness and the tapering of the external surface thereof, the side holding element hold the sheet material and, simultaneously, ensures that there is a gap between the winder tube and the sheet material wound on said tube, which facilitates its removal from the tube.

A compressed coreless rolled product is described, including an inner surface defining a central cavity having an inner diameter and an outer surface having an outer diameter larger than the inner diameter. The outer diameter is at least five inches and a ratio of the inner diameter to the outer diameter is at least 0.35. Also described is a compressed coreless rolled product with similar inner and outer surfaces, wherein: a difference between the outer diameter and the inner diameter defining a thickness of at least 2.9 inches; and a ratio of the inner diameter to the outer diameter is at least 0.35. An associated method of producing the product is also described, including steps of: winding an absorbent sheet around a forming core member; removing the forming core member to form a coreless rolled product with a diameter ratio of at least 0.35; and compressing the product.

An improved paper band delivery assembly for reliable high speed delivery of a turn-up paper band across a moving web of paper being wound onto a spool. The turn-up paper band is made ready for a turn up procedure by coiling a predetermined length of paper band suitable for a particular machine and retaining the coiled paper band in a reservoir pending deployment across a spool for a turn up procedure. The paper band may be coiled via manual operation or via automated operation. Coiling apparatus may be modularly replaced on a paper making machine. The coiled paper band may be supported within the reservoir on rollers, pins, or other items conducive to fast and reliable uncoiling.
