Machine (10) comprising a feed unit (16) configured to feed a plurality of tubular elements, preferably made of paper, toward different working units (18, 19, 20, 21) configured to automatically carry out different workings on the tubular elements (12), including a deformation to make a bellows (13), a cut to make a pointed end (14), or an end cut obliquely, a bending in correspondence with the bellows and a packaging of each straw, the deformation being carried out before the cut.

A cutting device for cutting-off pieces from an elongated workpieces, in particular a tube, having a proximal side, a distal side and a longitudinal axis extending between the proximal and distal side. The cutting device includes a cutting unit having a blade coupled with a blade drive. The blade is reversibly movable via the blade drive between retracted and advanced blade positions. The cutting device includes a proximal support structure arranged with respect to the longitudinal axis proximal of the blade and is configured to guide a distal part of the workpiece to be movable in parallel to and aligned with the longitudinal axis. The cutting device includes a feeder unit including a suction gripper configured for suction-coupling with the elongated workpiece. The feeder unit includes a suction gripper drive, coupled with the suction gripper, configured for moving the suction gripper parallel to the longitudinal axis in a reversible manner.

The invention relates to a cutting device (7) for cutting food products (e.g. pieces of cheese or sausage) into slices, with two parallel product feeders (8, 9) for feeding two food products into two conveyor tracks, and with two cutting blades (18, 19) for cutting the food products into slices. Furthermore, the invention comprises a corresponding operating method.

A log saw for cutting convolutely wound logs of web material is disclosed. The log saw comprises a cutting blade operating in a cutting plane, a log saw clamp for the retention of a convolutely wound log of web material such that the convolutely wound log of web material extends in a log advancing path through to the cutting plane, and control means connected to the clamping device.

A log saw clamp for temporarily restraining a convolutely wound log of web material for a log saw is disclosed. The log saw clamp comprises a support structure having a first and second cam disposed therein, a pair of opposed first and second paddles, and a first and second linkage.

An array of finished products, each finished product in the array having a length relative error of less than 0.81% of a target length, H is disclosed.

An apparatus for forming and sealing a duct member for use in an air handling system. At least one work station accommodates a work piece, which is generally a cylindrical tube.

The disclosure relates to a method for slicing food products formed as product calibers using a slicing machine, comprising: arranging multiple product calibers on a feeding unit, wherein at least two of the product calibers have different lengths, feeding, by the feeding unit, the at least two product calibers along a feeding direction to a cutting unit, and slicing, by the cutting unit, the at least two product calibers into slices to form portions, wherein each portion comprises one or more slices. The method further comprises determining, based on length of at least two product calibers a first slice thickness for a first product caliber of the at least two product calibers and a second slice thickness for a second product caliber of the at least two product calibers, wherein the first product caliber before slicing has a greater length than the second product caliber, and wherein the first slice thickness is determined to be greater than the second slice thickness, so that after slicing an equal number of portions from the first product caliber and the second product caliber a length difference between the first product caliber and the second product caliber is less than before slicing. The disclosure further relates to a slicing machine.
