The invention relates to a method for the decoating at least in part of blanks made of metal which are coated on one or both sides in regions, which have a main extension direction, wherein the regions to be decoated can extend in both a straight or curved manner in the main extension direction. The invention further relates to a device for the decoating at least in part of a coated blank in order to carry out the method according to the invention. A method is provided in which the blank is placed on a blank support of a press and during the closing movement of the press at least one scraping knife preferably completely removes the coating of the blank by scraping substantially perpendicular to the main extension direction of the region of the blank to be decoated.

Provided are a device and a method for ripping gum of a conveyor belt in which the burden and danger to workers can be reduced, and gum around each of the steel cords can be cut off nearly completely and sufficiently uniformly, regardless of worker skill, and with higher work efficiency. The device is for ripping gum of a conveyor belt in which individual steel cords embedded in gum of a conveyor belt are separated between each other, and gum is stripped off around each of the steel cords after the separation. The device includes a V-shaped cutting blade having a shape such that the upper end and the lower end of the cutting blade are protruded with respect to the traveling direction of the conveyor belt for separating between the individual steel cords, and a cylindrical cutting blade for stripping gum off around each of the steel cords.

Methods of producing an analysis spreading layer for absorbing a liquid to be analyzed, by: supplying a porous membrane having a bottom, a top and a thickness D, the size of the pores of the membrane increasing over its thickness D; cutting the membrane at a predefined distance, the spreading layer being a sublayer with a thickness d less than the starting thickness D, the pores of the spreading layer having a fluid connection to one another in such a manner that it is permeable to a liquid. The membrane surface is formed by removing a sublayer of the membrane being the liquid outlet side of the spreading layer. The mean size of the pores on the liquid outlet side is at least 1 μm.

A method and apparatus for producing sheets from the pseudostems of banana plants in the family Musaceae, each pseudostem having a longitudinal axis. The method includes the steps of feeding a pseudostem (14) into a workstation, supporting (62, 34) the pseudostem for rotation thereof about its longitudinal axis within the workstation, and contacting the rotating pseudostem along substantially its entire length with a fibre-separating device (38), whereby a continuous sheet of fibre (60) is removed from the pseudostem by the fibre-separating device during rotation. Raw paper may also be made by laminating two or more of these sheets together such that the direction of the generally parallel fibres in at least two adjacent sheets is not aligned and then curing the sheets to form raw paper.

A cable stripper apparatus is disclosed for stripping insulation from an electric cable. The apparatus includes a framework and a driven wire feeder rotatably secured to the framework. A guide is provided for guiding the cable towards the wire feeder. The guide includes a movable spacer bar which extends towards the wire feeder. A cutter has a cutting edge which is disposed spaced and parallel to an axis of rotation of the wire feeder. The cutter is connected to the framework immediately adjacent to the wire feeder. The arrangement is such that when the cable is guided by the guide towards the wire feeder, the wire feeder, spacer bar and the cutter cooperate with each other for stripping the insulation from the cable. A cam is rotatably supported by the framework for moving the movable spacer bar relative to the framework to a required location of a plurality of locations of the movable spacer bar. The cam defines a plurality of cam faces such that when the cam is selectively rotated, a corresponding cam face of the plurality of cam faces cooperates with and moves the spacer bar to the required location of the spacer bar for guiding a particular gauge wire towards the cutter.

Apparatus for continuously shaping a compressible or cellular polymer material, such as polyurethane foam, by cutting portions of the material from a surface of one or more slabs of material (180) includes two compression rollers (146, 146a), two moving patterned platforms (132, 132a) interposed between the compression rollers, and one or more cutting blades (76) for transversely cutting the slab or slabs just as the cellular material emerges from between the compression rollers. At least one of the moving patterned platforms, preferably an endless belt, defines a recess or pattern of recesses. When a single slab or multiple slabs of material are fed and compressed between the compression rollers, a portion of the material from one side of the slab or slabs fills the recess or recesses in one of the moving patterned belts. The blade then transversely cuts the cellular material.
