KNIFE STRIP, CUTTING BAR AND ADJUSTING DEVICE FOR THE SIMPLIFIED ADJUSTMENT OF THE KNIFE HEIGHT
A knife strip, cutting bar and adjusting device are provided by means of which an exact adjustment of the knife height is ensured for the entire service life of the adjusting device or of the knife bar, or by means of which the use of an adjusting device can even be forgone completely. An adjusting device includes a knife strip wherein at least one stop surface is formed in the area of at least one outer edge. An adjusting device includes at least one stop against which the at least one stop surface of the knife strip is placed. A knife bar includes at least one stop against which the at least one stop surface of the knife strip is placed.
Systems and methods for cutting label material
The present invention is an apparatus and method for cutting individual label strips from a roll of label web utilizing a cutter assembly. A label cutter comprises a cutter assembly for continuously and independently controlling the rotational speeds of a rotating cutter shaft, a stationary shaft, and a label feed roller is provided. The length of the label strip is controlled by the distinct speed of rotation of a stationary knife, the stationary knife is rotatably coupled to the stationary shaft. At least one cutter blade is operatively associated to the rotating cutter shaft for cutting the label web. The stationary knife rotates with a speed of rotation different from the speed of rotation of the cutter blade to produce longer or shorter label length strips. The frequency at which the cutter blade meets the stationary knife is inversely related to the length of the label strip that is produced during cut off.
Methods and apparatuses for separating discrete articles from continuous webs
Methods of separating discrete articles from continuous webs are disclosed. The methods use a separation assembly. The present disclosure further includes a cutting assembly and a pair of cutting rolls for use in the separation assembly.
Knife assembly for corrugated knife blade and cutting system equipped with same
A knife assembly including a corrugated knife blade, a holder, a clamp arranged for clamping the knife blade onto the holder, and a fastening mechanism for securing the knife blade between the clamp and the holder. The clamp has clamping parts along a clamping line rearward from the front edge. The clamp includes clamping geometrical elements, corresponding to complementary contact geometrical elements of the knife blade, positioned at least in part at a different distance from said front edge than the clamping line. The clamp engages the knife blade along the clamping line and at the corresponding contact geometrical elements.

Composite sheet manufacturing device and composite sheet manufacturing method
It is aimed to provide a composite sheet manufacturing device and a composite sheet manufacturing method capable of maintaining high cutting performance of a cutter by suppressing the adhesion of an adhesive of an adhesive surface to the cutter. A first sheet (42) introduced to between a cutter roller (2) and an anvil roller (3) is cut into strips (42a) while these rollers (2, 3) are rotated relative to each other, adhesive surfaces (a) of the strips (42a) are adhered onto a second sheet (43) for compounding, and at least one of a cutter (12) of the cutter roller (2) and the anvil roller (3) is cooled by a refrigerant by a cooling unit (20, 21).
Method for cutting, printing or embossing
The invention relates to an apparatus and method for cutting, printing or embossing a continuous sheet of material. The apparatus comprises a tool element, at least two anvils, which are co-operable with the tool element, and a phase adjustment device. The tool element is configured to have a constant surface speed during operation of the apparatus. The apparatus is adapted to receive the continuous sheet at a constant speed into the apparatus, and being adapted to output the continuous sheet at a constant speed from the apparatus. The phase adjustment device is operable to adjust a speed of the continuous sheet within the apparatus in order to adjust a phase of alternate parts of the continuous sheet to be cut, printed or embossed by each anvil as it co-operates with the tool element.
Orbital knife
An orbital knife including a support structure; a yoke rotatably attached to the support structure having a yoke hub and a plurality of yoke arms; one or more rotatable knife rolls connected to at least one of the plurality of yoke arms; one or more blades attached to each of the one or more knife rolls; one or more sun pulleys rotatably attached to the support structure; an anvil roll rotatably attached to the support structure; and one or more planet pulleys wherein (1) each knife roll has attached thereto at least one planet pulley, (2) each planet pulley is joined via a drive belt with one of the one or more sun pulleys wherein rotation of the sun pulley causes rotation of the planet pulley effectuated by the force imparted by the drive belt.
APPARATUS AND METHOD FOR THE PRODUCTION OF A CUSHION PRODUCT FROM A SINGLE- OR MULTI-LAYER CONTINUOUS PAPER STRIP
An apparatus for the production a cushion product from a single- or multi-layer continuous paper strip includes a feed unit for drawing the paper strip into the apparatus, a cutting unit for cutting the cushion product from the paper strip, and control electronics for the activation of the cutting unit according to a predetermined motion profile. A sensor captures a rotation angle position of the feed unit. The control electronics are configured to activate the feed unit continuously and to start an activation of the cutting unit for a discontinuous cutting operation during capturing a predetermined actual rotation angle position of the feed unit.
Corrugated cardboard plant
A corrugated cardboard plant comprises a corrugated cardboard web production assembly for producing a corrugated cardboard web; a register mark cutting device, disposed downstream of the corrugated cardboard web production assembly, for cutting the corrugated cardboard web into corrugated cardboard sheets; a register mark detection device, disposed upstream of the register mark cutting device, for detecting at least one register mark on the corrugated cardboard web; and a control assembly which is in signal connection with the register mark cutting device and with the register mark detection device, and depending on the at least one detected register mark actuates the register mark cutting device, while generating at least one register mark cut. The corrugated cardboard plant furthermore has a register mark cut position correction installation for the automatic correction of the position of the at least one register mark cut in relation to the at least one register mark in the case of an undesirable deviation of the position of the at least one register mark cut.
