UNIVERSAL FLOORING CUTTER
A cutting tool includes a base with a table surface and a cutting platform. The cutting platform is suspended above the table surface and includes a blade housing. The blade housing includes a blade holder with a linear blade. The blade holder is slidably connected through the base housing. A housing column is configured on the base of the cutting tool. A handle raises and lowers the blade. A guide rail is pivotally connected to the table surface by at least one releasable guide rail connector. The guide rail is releasably locked with respect to the blade at a plurality of angles.
Method for perforating a nonlinear line of weakness
A method for providing a nonlinear line of weakness on a web material including providing: a base, a support, a blade, and a driving means. The base may comprise at least one counter component having a length (L.sub.CC) where the counter component comprises a nonlinear shape having a shape width (W). The support may be operatively engaged with the base. The blade may have a length (L.sub.B) and may be disposed on the support so as to either contact or to come in close proximity with the counter component. At least one of the counter component and the blade may have a nonlinear shape. The driving means may be associated with one of the support or the base to reciprocally shift the one of the support or the base with respect to the other of the base or the support for a distance (D) in a shifting direction.

Cutting device and method for cutting paper
A cutting device and a method for cutting paper are provided. The cutting device includes a cutting blade and a counter-member. The cutting device is further provided with a first guide and a second guide extending in or parallel to the driving direction for linearly guiding a holder that holds the cutting blade. Each of the guides includes a guide body. The guide bodies of the first guide and the second guide, when released, are arranged to be rotatable relative to the frame about a first adjustment axis and a second adjustment axis, respectively. Each guide body includes an eccentric section that moves eccentrically about the respective adjustment axis and that is arranged to convert the rotational movement of the guides about the respective adjustment axes into a linear movement of the holder in the adjustment direction.
METHOD AND APPARATUS FOR ADJUSTING AND MAINTAINING A POSITION OF A CUTTING SURFACE OF A PERFORATING APPARATUS
The present disclosure relates to adjusting and maintaining a position of a cutting surface used to create lines of weakness for rolled products.
Bulk roll cutting apparatus with safety linkage and related methods
A bulk roll cutting apparatus with a safety linkage is used to prevent inadvertent gravitational falls of a blade. The apparatus has a frame holding the blade, the blade is movable between a cutting position and a retracted position. In the cutting position, the blade is positioned proximate to an arbor. At least one link arm is movably connected to the frame. An actuator connects between the at least one link arm and the blade. An adjustment device connects between the at least one link arm and the frame. The adjustment device controls a cutting depth of the blade relative to the arbor. A safety linkage connects between the at least one link arm and the frame, and the safety linkage prevents an inadvertent gravitational fall of the blade.
CUTTER HOLDER FOR MICROTOME
The present disclosure relates to a cutter holder for a microtome. The cutter holder includes: a base; a pressing plate pivotably mounted to the base and having a first end configured to clamp the cutter; an eccentric shaft rotatably mounted in the base; and a sliding assembly slidably mounted in the base. The sliding assembly is arranged between the pressing plate and the eccentric shaft and is in contact with the eccentric shaft, and the sliding assembly is movable towards the pressing plate when the eccentric shaft rotates, so as to force the first end of the pressing plate to clamp the cutter with the base. The cutter holder according to embodiments of the present disclosure allows easy mounting and replacement of the pressing plate, facilitates clamping of the cutter and regulation of a clamping force, and has high working efficiency and high reliability.
KNIFE ASSEMBLIES OF SLICING MACHINES, METHODS OF CLAMPING AND RELEASING KNIVES THEREFROM, AND SLICING MACHINES EQUIPPED THEREWITH
Knife assemblies for securing knives to slicing machines, slicing machines equipped therewith, and methods of operating knife assemblies for securing knives to and releasing knives from slicing machines. Such a knife assembly includes a knife holder having a knife support surface, a knife supported on the knife support surface, and a clamp having a base portion adjacent a trailing edge of the clamp and a knife-engaging portion adjacent a leading edge of the clamp. The knife assembly applies a clamping load to the clamp to secure the knife to the knife holder. The clamp is prevented from translating relative to the shaped knife in a leading direction of the knife assembly as the clamping load is applied and/or permits removal of the clamp by being translated in the leading direction.
Automated fiber placement (AFP) cutter blade assemblies, AFP cutter systems including the same, and associated methods
Automated fiber placement (AFP) cutter blade assemblies, AFP cutter systems including the same, and associated methods. An AFP cutter blade assembly includes a blade base and a reversible blade insert configured to be coupled to the blade base in either of a first cutter blade configuration, in which a first cutting edge is an active cutting edge, and a second cutter blade configuration, in which a second cutting edge is the active cutting edge. In examples, an AFP cutter system includes a plurality of AFP cutter blade assemblies in combination with an actuator assembly. In examples, a method of reconfiguring a reversible blade insert of an AFP cutter blade assembly includes uncoupling the reversible blade insert from a blade base, rotating the reversible blade insert relative to the blade base, and operatively coupling the reversible blade insert to the blade base in a different configuration.
ROTARY DIE CUTTING DEVICE AND METHOD FOR SETTING A GAP DIMENSION OF A GAP BETWEEN A DIE CUTTING CYLINDER AND A COUNTER PRESSURE CYLINDER OF THE ROTARY DIE CUTTING DEVICE
A method for setting a gap dimension of a gap between a die cutting cylinder and a counter pressure cylinder of a rotary die cutting device includes providing a control system including a controller, at least one sensor, and an adjusting device actuated by the control system. The method further includes actuating the adjusting device in response to the at least one sensor sensing a deviation from a desired state, thereby setting the gap dimension between the rotary die cutting device and the counter pressure cylinder, in which actuating the adjusting device is achieved as a result of the control system operating in a closed feedback loop. The method further includes sensing by the at least one sensor occurring with or without disruption of operation of the rotary die cutting device.
