Patent ID: 8176821

Claim:
A machine for processing a sheet for production of packagings, the machine comprising: a machine entrance, a machine exit and a processing zone positioned between the machine entrance and the machine exit, the processing zone including a sheet path; a sheet drive operable to drive sheets in a drive direction and at a substantially constant drive speed through the processing zone; a processing apparatus comprising a first tooling including blades, the first tooling supported by a first rotary support shaft and a counter-tooling supported by a second rotary support shaft, the first rotary support shaft and the second rotary support shaft extending transversely to the drive direction and positioned opposite each other and respectively on one and the opposite side of the sheet path, the processing apparatus being operable to produce at least one of a cutout and a fold disposed in the sheets transverse to the drive direction; an operating apparatus for rotationally driving the first rotary support shaft and the second rotary support shaft so that at least at a moment when the first tooling and the counter-tooling cooperate with the sheet to make the at least one of the cutout and the fold, the first tooling is rotating at a processing speed having a tangential component equal to the drive speed, and the counter-tooling is situated opposite the first tooling; the counter-tooling having a substantially cylindrical surface comprising at least one working strip positioned thereon, the at least one working strip extending in length parallel to a rotation axis of the second rotary support shaft and being radially offset relative to portions of the cylindrical surface adjacent to the at least one working strip, the at least one working strip being shaped and positioned to cooperate with the first tooling to form the at least one of the cutout and the fold; the at least one working strip having a width in a circumferential direction greater than a width of the first tooling; the at least one working strip comprising a flexible material to allow the blades of the first tooling to penetrate into said at least one working strip; and a first motor drive operable to drive the first rotary support shaft and a second motor drive operable to drive the second rotary support shaft such that the second motor drive is operated as a slave to the first motor drive, wherein the working strip includes a top surface radially offset at a first height relative to the portions of the cylindrical surface immediately adjacent the at least one working strip, and an auxiliary surface positioned immediately adjacent the top surface along the width in the circumferential direction of the working strip, the auxiliary surface being radially offset at a second height relative to the portions of the cylindrical surface immediately adjacent the at least one working strip, wherein the first height is greater than the second height.
