The invention relates to a method for winding up a web of material (4) by means of an apparatus (1) including at least: one winding-up space (2) for accommodating an at least partially wound up web of material (wound roll (3)) having a winding center (Z); means for conveying and/or manipulating the web of material prior to and/or during winding-up; including the following steps: a) operating the apparatus (1); b) monitoring the web of material (4) and/or the resulting wound roll (3) by means of at least one image capturing device (30) for obtaining at least one current state (actual state) of the web of material (4) and/or of the wound roll (3); c) comparing at least one actual state to at least one target state and corresponding to the actual state, and determining at least one deviation of the actual state from the corresponding target state; d) if the deviation exceeds/falls below at least one predetermined limit value, performing a correction of at least one operating parameter of the apparatus (1) which operating parameter is at least a contributing factor for the deviation.

A rewinding machine and a related method, the machine including three rollers having axes parallel to one another and perpendicular to the advancing direction of the paper, where two lower and upper winding rollers collaborate with a third oscillable roller under pressure on a roll or log being formed identifying a winding area, where the paper being wound passes over the upper winding roller and the finished roll comes out from an outlet opening defined between the lower roller and the third roller, where the cores for the rolls are fed one after the other by a conveyor and inserted by a thruster in a channel formed beneath the upper roller, the lower and upper winding rollers being supported in rotation at the ends of their axes in a mobile manner and being associated with an actuator device for a translation in a direction parallel to a first straight line joining the axes of the lower and upper winding rollers and symmetrical with respect to a growth straight line of the roll, where the growth straight line of the roll is arranged perpendicular to the first straight line joining the two axes of the lower and upper winding rollers and equally spaced between them.

A core member is provided for storing shrink film. The core member includes a plurality of rollers, each having a disc and a core extending upwardly from the disc. The plurality of rollers are aligned longitudinally along an axis and laterally along a plane. The plurality of rollers are rotatable to wind the shrink film about the rollers.

A spindle assembly for supporting a roll of paper product is disclosed with features that make the spindle versatile and useable for supporting paper product rolls in a plurality of styles of dispensers. The spindle assembly also includes features that assist in maintaining the supported paper rolls in a desired orientation, such as horizontally in a vertically oriented dispenser. This resists skewing of the rolls in the dispenser and facilitates the separation of the rolls as paper is used from a lower roll in a dispenser. Also, brake members are provided to engage the core of a supported roll of paper to slow down the rotation of the roll of paper when pulled upon by a user.

A manufacturing method includes: a first step for winding up paper to form paper roll; a second step for inserting an insertion section, which ejects an adhesive, into a center hole of the paper roll; a third step for causing the adhesive to adhere to a predetermined position of the center hole; and a fourth step for performing a heating and drying process on an area to which the adhesive is adhered to harden opposite ends of the center hole. The third step includes causing the adhesive to adhere to near opposite extending ends of the center hole. The adhesive has adhesive strength to an extent that the paper wound up into the roll shape is peelable when the paper roll is to be used. The fourth step includes drying the adhesive adhered to the center hole before the adhesive spreads from the predetermined position of the center hole.

A core member is provided for storing shrink film. The core member includes a plurality of rollers, each having a disc and a core extending upwardly from the disc. The plurality of rollers are aligned longitudinally along an axis and laterally along a plane. The plurality of rollers are rotatable to wind the shrink film about the rollers.

A rewinding machine and a related method, the machine including three rollers having axes parallel to one another and perpendicular to the advancing direction of the paper, wherein two lower and upper winding rollers collaborate with a third oscillable roller under pressure on a roll or log being formed identifying a winding area, wherein the paper being wound passes over the upper winding roller and the finished roll comes out from an outlet opening defined between the lower roller and the third roller, where the cores for the rolls are fed one after the other by a conveyor and inserted by a thruster in a channel formed beneath the upper roller, the lower and upper winding rollers being supported in rotation at the ends of their axes in a mobile manner and being associated with an actuator device for a translation in a direction parallel to a first straight line joining the axes of the lower and upper winding rollers and symmetrical with respect to a growth straight line of the roll, where the growth straight line of the roll is arranged perpendicular to the first straight line joining the two axes of the lower and upper winding rollers and equally spaced between them.

A wrapping material roll includes a flexible sheet having a length and a width. The sheet is rolled concentrically about an axis parallel to the direction of the width such that a longitudinal end of the sheet is located along a circumferential side of the wrapping material roll. At least a part of the longitudinal end is folded along a folding line over at least part of the width.

The invention relates to a method for winding up a web of material with an apparatus including one winding-up space having a winding center; means for conveying and/or manipulating the web of material prior to and/or during winding-up; and including the following steps: operating the apparatus; monitoring the web of material and/or the resulting wound roll by means of at least one image capturing device for obtaining at least one current state of the web of material and/or of the wound roll; comparing at least one actual state to at least one target state and corresponding to the actual state, and determining at least one deviation of the actual state from the corresponding target state; if the deviation exceeds/falls below at least one predetermined limit value, performing a correction of at least one operating parameter of the apparatus which operating parameter is at least a contributing factor for the deviation.
