A carrying device includes: a carrying section having a receiving surface to be in contact with a first sheet material that is continuous in a carrying direction, wherein one edge of the first sheet material is wave-shaped, the carrying section defining an inclined slit portion, wherein the inclined slit portion defines an opening on the receiving surface, wherein the inclined slit portion extends in an inclined direction so as to be displaced from a proximal side toward a distal side of a protruding portion while extending downstream in the direction of carrying the first sheet material, and wherein the inclined slit portion sucks the protruding portion along the wave-shaped edge; and a box defining a suction space that keeps the inclined slit portion under a negative pressure so that the protruding portion is pulled into the inclined slit portion by suction.

An interleaving unit, comprising a pair of rolls (1, 2) set alongside one another and counter-rotating and provided with respective first and second folding tools (3, 4; 5, 6) set at a distance from one another along the circumferential development of the respective peripheral surfaces so as to operate in a common point of tangency (Z) on a succession of sheets (7a, 7b) fed between the two rolls, said tools (3, 4; 5, 6) being set on respective mobile cylinder sectors (8, 9, 10, 11) to enable positioning thereof at an adjustable distance apart along the circumferential development of a corresponding roll (1, 2), said interleaving unit comprising means (M1, M2, U) for independently adjusting the speed of rotation of one or more of said sectors according to their angular position in order to reduce or increase the peripheral speed of said sectors with respect to a speed of feed (Vm) of said sheets.

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 device for treating substrates has a separation system, with which processed substrates can be separated into one or more waste parts and at least one blank. The device for treating substrates offers improved flexibility. The separation system comprises a transport cylinder and a stripping cylinder associated therewith. The transport cylinder is able to secure replaceable packing, along with first and second openings which, when the packing is secured, are covered at least partially by perforations that may be formed in the packing. A first air supply supplies air to the first openings and a second air supply supplies air to the second openings independently of the supply of the air to the first openings. The first and the second air supply are switchable between a suction air supply and a blower air supply.

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.
