When a remaining amount of a sheet on one original sheet roll is equal to or less than a predetermined remaining amount, a pair of holding pads is brought into a first posture where holding surfaces are opened, and the holding surface of one holding pad is pressed to a joining end portion from the outside of the original sheet roll in a radial direction of another original sheet roll. Further, the holding pad is moved such that the joining end portion is separated toward the outside of the original sheet roll in the radial direction. Further, the posture of the pair of holding pads is changed into a second posture where the holding surfaces approach each other, and the joining end portion is conveyed to a joining part in a state where the joining end portion is sandwiched between the holding surfaces of the pair of holding pads.

A method for providing rolls of material for use in sheet form, particularly aluminum for food uses, comprising a step of rewinding the material for use in sheet form in order to form a roll; the rewinding step is provided by winding the material for use in sheet form directly on a rewinding shaft, with the material for use in sheet form in contact with a cylindrical outer lateral surface of the rewinding shaft, which is actuated with a rotary motion about its longitudinal axis, so as to obtain a coreless roll.

Folding or interfolding unit of a web, or sheet, of paper, comprising a first and a second folding or interfolding roll, of a web, or sheet, of paper, configured to fold or interfold, the web or sheet of paper according to a predetermined folding or interfolding configuration, at a folding or interfolding zone arranged between the first and the second folding or interfolding roll. The folding or interfolding unit comprise, furthermore, a first and a second plurality of detaching fingers configured to cause the web or sheet of paper to be detached from the external surface of the respective folding or interfolding roll.

The disclosure relates to a method and apparatus for uncut material detection while lifting from an automated cutting table select pieces of thin, flexible material. The apparatus comprises a structured energy source and a structured energy sensor. The structured energy can be used to detect undesired lifting of a peripheral portion of the flexible material resulting from the presence of uncut material.

A sheet delivery system includes: an end section detector which detects a position of an end section of a sheet; an end section conveying apparatus which holds the end section of the sheet and which conveys the end section of the sheet to a joining unit; a roll driving motor which rotationally drives a standby-side original material roll around a central axis thereof; and a suction roller which is capable of coming into rolling contact with an outer peripheral surface of the standby-side original material roll, and which includes an outer peripheral surface capable of suctioning the end section of the sheet in order to separate the end section of the sheet from the standby-side original material roll. The end section detector is attached at a position which enables detection of the end section of the sheet separated from the standby-side original material roll by the suction roller.

When a remaining amount of a sheet on one original sheet roll is equal to or less than a predetermined remaining amount, a pair of holding pads is brought into a first posture where holding surfaces are opened, and the holding surface of one holding pad is pressed to a joining end portion from the outside of the original sheet roll in a radial direction of the other original sheet roll. Further, the holding pad is moved such that the joining end portion is separated toward the outside of the original sheet roll in the radial direction. Further, the posture of the pair of holding pads is changed into a second posture where the holding surfaces approach each other, and the joining end portion is conveyed to a joining part in a state where the joining end portion is sandwiched between the holding surfaces of the pair of holding pads.

A joining unit includes: a suction holding member having a suction surface configured to suction an end section of a sheet; a moving mechanism configured to move the suction surface toward an intermediate section of a sheet of a delivery-side original material roll along a path set in advance so that tension is applied to the sheet; and a regulating mechanism that is configured to switch between a regulated state in which a movement of the end section of the sheet with respect to the suction holding member due to the tension is regulated and an allowable state in which the movement of the end section of the sheet with respect to the suction holding member is allowed. The controller switches the regulating mechanism to the regulated state during the movement of the suction surface toward the intermediate section of the sheet of the delivery-side original material roll.
