The invention relates to a method for producing a stamped metal sheet which has at least one interrupted cutting line in (17) for producing perforations or holding points, which is arranged on a base sheet (15), characterized in that a laser beam is used for producing at least one interruption (14). The invention also relates to a stamped metal sheet.

A text concealing tool assembly for defacing text from a paper includes a handle and a cover that is attached to the handle. A defacing unit is rotatably mounted in the cover. The defacing unit is rolled over a paper to mark and pierce the paper such that writing on the paper is illegible.

provided is a method for manufacturing a mold element for the production of microarrays, including the following steps: (i) providing a planar base element having a first surface and a second surface opposite the first surface, (ii) providing a planar auxiliary element on the second surface, (iii) penetrating the base element from the first surface in order to form mold openings, and (iv) reversibly or non-reversibly entering the auxiliary element when penetrating the base element. Moreover, a mold element for the production of microarrays, including a planar base element having a first surface a second surface opposite the first surface, a planar auxiliary element arranged on the second surface, and several mold openings extending from the surface of the base element through the second surface of the base element.

A slitter device comprising a circular blade at an outer periphery of the slitter device. One or more row of transverse blades at the outer periphery and on a side of the circular blade, the blades of the row of transverse blades being oriented transversely relative to the circular blade.

A surgical stapler is described herein which includes a shaft portion and a tool assembly supported on a distal end of the shaft portion. The too assembly includes an anvil and a cartridge body which rotatably supports a plurality of staples within notches. At least one firing cam is provided to sequentially to engage and rotate each of the staples to fire the staples from the cartridge body. In embodiments, the cartridge body includes two spaced legs which support two linear rows of staples. Each of the spaced legs of the cartridge body is supported within one of a first and a second cartridge channel. The cartridge channels are fixed to opposite sides of a pivot member which is pivotally supported at a distal end of the shaft portion between the shaft portion and the tool assembly such that translation of the first and second cartridge channels in opposite directions effects articulation of the tool assembly in relation to the shaft portion.

A method for checking the correct operation of a pre-cutting device in a plant for production of logs of paper material. The method includes realization and assembly of the pre-cutting device, with relative positioning and adjustment of said first and second element; activation of the pre-cutting device with the measurement of the vibrations emitted relating to the interaction between said first and said second element; storage of at least a value or of a set of values relative to the measurement of the vibrations corresponding to an optimal or reference operating configuration of the device; measuring, the values of the vibrations emitted by the interaction between said first and second element and comparison with the value or set of values related to the reference operating configuration, with the emission of a signal if there is a non-correspondence between the detected value and the reference value or set of reference values.

A roll of sanitary tissue product that includes a shaped line of weakness, wherein the roll of sanitary tissue product exhibits a roll compressibility of from about 7%, and the sanitary tissue product has a Full Sheet Average Trapezoidal Tear Strength of about 8 g to about 20 g, as measured by the Full Sheet Average Trapezoidal Tear Force Method.

A packaging line station having a frame, a die assembly, a drive motor, and an anvil roller. The frame has a base with two vertical stanchions extending upwardly from sides thereof and a top cross-member affixed across the stanchions. The die assembly includes a yoke affixed to the cross-member, a die wheel rotatably affixed to side arms of the yoke, a drive shaft affixed to the die wheel and a cutting die affixed to the die wheel. The drive motor is connected to the drive shaft. The drive shaft and the anvil roller extend between the stanchions. The cutting die and the anvil roller and spaced apart by a nip for receiving a traveling web. As the web passes through the nip the web is cut by blades of the rotating die to form a slit. An adhesive resealable tape or label is then applied over the slit.

The present invention relates to a method for making an aperture web, comprising moving a micro-textured web through a first member comprising male elements and a second member comprising discontinuous female elements, wherein the male elements are arranged in a staggered pattern, and have a shape to form quadrilateral apertures in the micro-textured web. The present invention also relates to a method for making an aperture web, comprising forming microtextures on a web, and continuously moving the web through a first member comprising male elements and a second member comprising discontinuous female elements, wherein the male elements are arranged in a staggered pattern, and have a shape to form quadrilateral apertures in the micro-textured web.
