A sheet material processing unit (10) is described. It comprises an upper tool (18) and a lower tool (14), wherein the upper tool (18) and the lower tool (14) are configured to interact with each other in order to process sheet material (26). Furthermore, a camera unit (40) is provided which is arranged such that it is able to simultaneously capture a portion of the upper tool (18) comprising a first opening (28) and a portion of the lower tool (14) lying behind the first opening (28) for aligning the tools (14, 18). The sheet material processing unit (10) additionally comprises a first and a second set of light sources which are distinct from one another and are configured for subsequently illuminating the portions to be captured. Moreover, methods for assessing an alignment of the upper tool (18) with respect to the lower tool (14) and with respect to the sheet material (26) are presented.

This application relates to a fixed blade monitoring structure and a cutting device used for lithium battery manufacturing. The fixed blade monitoring structure includes: an anvil, fixed blade die set, and a fixed blade monitoring assembly. A sliding sleeve is disposed on the anvil. The fixed blade die set includes a fixed blade holder and a fixed blade mounted on the fixed blade holder. An end of the fixed blade holder is slidably mounted in the sliding sleeve. The fixed blade monitoring assembly is mounted in the sliding sleeve and connected to the fixed blade holder, and configured to render status of the fixed blade by monitoring a relative force received by the fixed blade holder. Through the above structure, manpower and time consumption in the tuning process is reduced. The status monitoring of a first cutter and a second cutter can be implemented during the cutting.

The disclosure relates to a device for shredding strip-shaped material comprising a housing with at least one feed opening for the strip-shaped material and a discharge opening for the shredded material, a blade holder which is mounted to be rotatable about an axis within the housing, at least one blade which is attached to the blade holder, at least one counter blade which is attached to the housing, and a drive configured to rotate the blade holder in a first direction of rotation and a second direction of rotation, opposite to the first direction of rotation, about the axis. The disclosure further relates to a method for operating a device for shredding strip-shaped material. Under the method, at least one blade holder mounted to be rotatable in a first direction of rotation, as well as in a second direction of rotation, is employed by the device.

A shearing method of a plate-shaped workpiece for applying a shear force in a thickness direction of the plate-shaped workpiece includes: a step for starting applying the shear force on the workpiece with a clearance between action points in a surface direction orthogonal to the thickness direction of the workpiece; a step for applying the shear force after the start of applying the shear force until a fractured surface is created in the workpiece; and a step for increasing the clearance depending on a deformation of the workpiece in the thickness direction after starting applying the shear force until the fractured surface is created in the workpiece.

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.

A beverage container handling machine, such as a beverage container filling machine or a beverage container closing machine, is used to handle beverage bottles, cans, and similar containers, which containers are configured to hold or contain a beverage, such as water, soft drinks, beer, wine, and juices, or a similar product for transport and consumption by consumers of beverages and similar products.

A shearing device (1) having a blade (2) with at least one blade cutting edge (5) which is helically coiled, and rotatable, about an axis of rotation (R) of the blade (2). The blade cutting edge (5) is assigned a counterpart blade cutting edge (4) of a counterpart blade (3). The shearing movements, by which for example bristle filaments (7) of brushes (8) for machining can be cut to length, are generated by relative rotational movement of the at least one helically coiled blade cutting edge (5) with respect to the preferably static counterpart blade cutting edge (4) of the counterpart blade (3). Since the blade (2) and the counterpart blade (3) can keep their spacing to one another constant during operation, there is a relatively low risk of injury during the use thereof.

A cutting machine has a cutting support for material to be cut, with a vertically movable blade bar which bears a blade for cutting the cut material located thereon. A cutting drive is for vertically moving the blade bar. A blade depth adjustment is for vertically adjusting the blade bar relative to a vertically movable drive element of the cutting drive. The blade depth adjustment includes a deflection lever which is pivotably mounted about a horizontal axis on the blade bar. The drive element can be articulated thereon at a first radial distance to the horizontal axis. An adjusting mechanism may act on the deflection lever at a second radial distance to the horizontal axis, for rotating and fixing the deflection lever.

A method for providing a nonlinear line of weakness on a web material includes: providing a counter component comprising a nonlinear shape, where the nonlinear shape has a shape width, W; providing a blade in operative relationship with the counter component and comprising a plurality of teeth; rotating at least one of the blade and the counter component into interacting relationship with the other of the blade and the counter component; feeding a web between the counter component and the blade such that while in interacting relationship the blade cooperates with the counter component to perforate the web, wherein the web is moving in a machine direction; and reciprocally shifting one of the counter component and the blade for a distance, D, in a shifting direction, wherein D is at least the translational distance that one tooth travels to cover the shape width, W.
