Abstract: 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.

Abstract: A converting line for coreless roll products includes a rewinding machine and a controller. A log of convolutely wound web material is wound in the rewinding machine during a wind cycle. A diameter of the log, a caliper of the web material, and an amount of tension of the web is determined at a plurality of time points during a time period of the winding cycle. The controller is enabled to generate a signal to change an operating condition of the converting line based upon at least one of a diameter determination at a time point during the wind cycle, a caliper determination at a time point during the wind cycle, a wound web amount determination at a time point during the wind cycle, and a tension determination at a time point during the wind cycle.

Abstract: An embosser/laminator machine has an adhesive unit releasably connectable with a main frame structure of the machine, and a roll extractor configured to move a roll between the main frame structure and an exchange position between the main frame structure and the adhesive unit when the adhesive unit is spaced from the main frame structure during removal and installation of the roll. The sub-frame comprising the adhesive unit may be formed with a bearing cap that cooperates with the main frame structure such that when the adhesive unit is connected with the main frame structure, the roll is operatively secured to the machine between main frame structure and the sub-frame of the adhesive unit for normal operation of the machine. When the sub-frame comprising the adhesive unit is released and spaced from main frame structure, the roll may be removed from and installed into the main frame structure.

Abstract: A flexible mandrel is provided for holding cores or core segments so that a roll of sheet material can be wound on the core segments in a winding machine. The mandrel and core segments are coupled through elastic interference between the mandrel and the core segments so that the core segments are arranged either adjacent to each other or spaced apart. A method for producing rolls of sheet material on the novel combination of mandrel and core segments feeds cores in an apparatus, transversely cuts the cores to form portions of core or core segments, feeds a flexible mandrel into the core segments for supporting and maintaining the axial position of the core segments. Coupling is by elastic interference between the flexible mandrel and the core segments to form an assembly in which the core segments are arranged on the mandrel spaced apart or adjacent one to the other.

Abstract: Remotely actuated robotic wrist for applications in the field of teleoperation, for example for mininvasive surgical operations, comprising a distal element (3) mounted on a support (2) capable instantaneously to rotate with respect to a fixed member (5), for example by a ball joint (10) that allows three rotational degrees of freedom. In particular, the support (2) can be oriented with respect to the fixed member (5) with a redundant actuating system by arranging four forces in eccentric points, for example by means of tendons (8), and causing the rotation of the support (2) about the central post (5) by the ball joint (10). Alternatively, the support (2) can be oriented with respect to the fixed member (5) by a mechanism that reproduces the rolling of a mobile sphere, which belongs to the support, on a fixed sphere, integral to the fixed member.
