The suction opening (111) is formed and arranged such that the air flow (114) passes the suction opening (111) so that air flow (114) entrains air through the suction opening (111).

A cutting machine that includes a knife and an unrolling device. The knife severs foodstuff slices from a foodstuff bar. A leaf from a separating material is provided between at least two foodstuff slices. The unrolling device providing the separating material for disposal of the leaf between the two foodstuff slices and injecting the leaf into the cutting region. The unrolling device has a tape roll and a delay unit. The delay unit along a transporting movement of the separating material is disposed downstream of the tape roll. The delay unit is configured for delaying the transporting movement of the separating material, which is unrolled from the unrolling device and is provided in a cutting region of a cutting machine. The delay unit has a pressure-generating means for exerting pressure on the separating material, and a suctioning means for suctioning the separating material by means of negative pressure.

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.

A guide member (14) has an upper surface assisting conveyance of workpieces (44) mounted on a table (12) and is arranged downstream of the table (12) in a workpiece conveyance direction. A belt drive mechanism (16) has pulleys (26a to 26d, 28a to 28b), and endless belts (32a to 32d) wound around these pulleys, and is arranged above the table (12) and the guide member (14) so as to stride over the table (12) and the guide member (14).
