The invention relates to a packaging machine comprising an apparatus for cutting food packagings to size along a longitudinal direction, wherein the apparatus defines an inner space and an outer region, said apparatus having a first shaft, which extends in the inner space and on which at least a first cutting blade is arranged, and a second shaft which extends in the inner space and on which at least a second cutting blade is arranged, said second cutting blade forming a cutting unit arranged in the inner space together with the first cutting blade during operation, wherein the first cutting blade is axially displaceably supported on the respective shaft to change an axial spacing and an axial contact pressure between the first cutting blade and the second cutting blade of the cutting unit, and said apparatus having an adjustment mechanism, wherein the adjustment mechanism is coupled to the axially displaceable first cutting blade to displace the displaceable cutting blade in an axial direction. The invention furthermore relates to a method of setting a contact force between a first cutting blade and a second cutting blade of a cutting unit of a packaging machine.

A cutting apparatus cuts a workpiece by a cutting blade. The cutting apparatus includes a mount flange on which the cutting blade is mounted and a replacement apparatus that replaces the cutting blade mounted on the mount flange with the cutting blade for replacement. The replacement apparatus includes a rotating part, a first holding part that holds the cutting blade mounted on the mount flange on a front surface side, a second holding part that holds the cutting blade for replacement on a front surface side, and a nut rotation part that has a nut holding part that holds a nut for fixing the cutting blade to the mount flange and rotates the nut held by the nut holding part. The rotating part is coupled to the first holding part, the second holding part, and the nut rotation part.

The invention relates to a blade receiver assembly, comprising a switch comprising a switch cover and a switch base fixedly connected to each other, wherein the switch base has an opening; an axle with a structural section and a body receiver section, wherein the axle is arranged to move through the opening of the switch base in relation to the switch. The invention also relates to a cutting device comprising a blade receiver assembly.

A cutting apparatus includes a cutting unit that has a spindle with an annular cutting blade mounted to a tip part of the spindle through a blade mount, and a determining unit. The determining unit has a second flow path that is connected to a first flow path in a mounter of the blade mount for causing a negative or positive pressure to act on the first flow path, a measuring device that obtains a measured value of at least one of a pressure and a flow rate in the second flow path, and a screw-engaged state determining section that determines that a screw-engaged state of a fixed nut with a boss section of the mounter where the cutting blade is disposed is defective in a case where the measured value when the negative or positive pressure acts on the first flow path indicates an abnormal value.

The present invention provides a light-weight spacer for a slitting machine for maintaining the width between slitting knives. The light-weight spacer comprises: a spacer body having a ring structure integrally formed of metal; an inner surface positioned on the inner side of the ring structure and extending along the central axis of the ring structure; an outer surface positioned on the outer side of the ring structure and extending along the central axis of the ring structure; a first side surface extending between the inner surface and the outer surface and being perpendicular thereto; a second side surface opposite to the first side surface and extending between the inner surface and the outer surface; a first plurality of perforations provided on the first side; and a second plurality of perforations provided on the second side.

A blade mounting and removal tool, and system, for safely removing a blade from a food product slicer.

A mount flange for mounting a cutting blade on a spindle is provided. The cutting blade has a central engaging hole and a peripheral cutting edge. The mount flange includes a cylindrical boss portion having a front portion adapted to be inserted into the engaging hole of the cutting blade and a rear portion whose inner circumferential surface is adapted to be engaged with the spindle, and a flange portion projecting radially outward from the rear portion of the boss portion and having a front surface functioning as a mounting surface adapted to come into abutment against one side surface of the cutting blade. An annular space is formed in the mount flange so as to surround the spindle and open to the inner circumferential surface of the boss portion, thereby suppressing rearward warpage of the outer circumference of the flange portion due to the rotation of the spindle.

An automated glass scoring device and a pillar post are provided. The pillar post includes a body having a fluid inlet port, at least one internal passage, a fluid exit port, and a fluid flow metering element. At least a portion of the fluid flow metering element is disposed within the internal passage. The at least one internal passage provides a path for a fluid flow from the inlet port to the fluid exit port, and the fluid exit port is positioned such that the fluid flow exiting the fluid exit port exits in close proximity to the cutter wheel.

The cutting machine for cutting logs of web material, includes a cutting head arranged along the feeding path of the logs. The cutting head includes a coupling for a disc-shaped cutting blade and is designed to impart the disc-shaped cutting blade a rotary motion around the axis thereof and a cyclic movement to cut the logs into single rolls, and to allow the logs to move forward along the feeding path. The machine also includes a store unit for disc-shaped cutting blades associated with the cutting head. A handling member is provided to remove a worn disc-shaped cutting blade from the cutting head and replace the worn disc-shaped cutting blade with a new disc-shaped cutting blade taken from the store unit.

The invention relates to an interface between a knife and a knife holder, wherein the knife and the knife holder are designed such that the knife can be mounted on the knife holder in such a way that the knife is initially positioned on the knife holder in the axial direction, and then by rotating either the knife relative to the knife holder and/or the knife holder relative to the knife, the knife is locked on the knife holder with respect to the axial direction, wherein the knife has a single central fastening opening which is delimited by a knife edge region, and the knife holder has a fastening section for the fastening opening of the knife, which is delimited by a holder edge region.
