Patent number: 10105822Abstract: A holding device, in particular a grinding disc, for a grinding member includes at least one support member that has at least one material opening configured for transverse transport of grinding dust to one side facing the grinding member in a plane parallel to a grinding surface. The holding device further includes at least one securing layer configured to secure the grinding member on the at least one support member. When decoupled from the grinding member, the at least one material opening is at least substantially open on a side facing the grinding member and on a side facing away from the grinding member is substantially delimited by the support member.Type: GrantFiled: June 5, 2014Date of Patent: October 23, 2018Assignee: Robert Bosch GmbHInventors: Stefan Christen, Thomas Emler, Beat Eugster, Stephan Fritsch, Michael Gaenzler, Roman Zaech, Adrian Schoch, Peter Eggenberger

Patent number: 9821432Abstract: An exchangeable abrasive mechanism or disc for use on abrasive-mechanism carriers having suction holes includes a plurality of through openings that each have a centroid. The through openings are differentiated into three groups that differ in the radial disposition of the centroids. A first group comprises at least one, but not more than four, through openings of a first cross section. At least two of the through openings of the first group are disposed on a first circumcircle diameter that is substantially identical to one of the hole-circle diameters such that, when the abrasive mechanism is correctly disposed on an abrasive-mechanism carrier, they are in direct alignment with and can overlap, two corresponding suction holes. A second group of through openings of a second, preferably smaller, cross section, comprises at least four through openings that are disposed on a second circumcircle diameter that differs from the first circumcircle diameter.Type: GrantFiled: August 13, 2013Date of Patent: November 21, 2017Assignee: Robert Bosch GmbHInventors: Josef Breitenmoser, Stephan Fritsch

Patent number: 9744648Abstract: A mounting element for holding a self-adhesive and/or flexible abrasive includes a supporting plate, and a distributing body. The supporting plate includes a plurality of suction openings which penetrate the supporting plate from a first side to a second side opposite the first side. A first side of the distributing body is in contact with the second side of the supporting plate, and a second side of the distributing body is configured to hold an abrasive. The distributing body includes a plurality of cavities which penetrate the distributing body from the first side of the distributing body to the second side of the distributing body, and which are mutually separated by a plurality of walls. At least one of the walls has at least one aperture which connects at least two adjacent cavities to each other.Type: GrantFiled: December 9, 2014Date of Patent: August 29, 2017Assignee: Robert Bosch GmbHInventors: Stephan Fritsch, Adrian Schoch, Juerg Schnyder

Patent number: 9415969Abstract: A method for controlling a feeder of a gathering-stitching machine reduces the operating effort when setting the feeder, increases reliability when laying folded sheets on a transport device and improves quality during collating and stitching. Opening and closing times of grippers are regulated under program control, continuously and as a function of format when controlling the feeder of the gathering-stitching machine. Data relating to the dimensions and to the number of pages of the folded sheets is thus entered into a control device, from which data actuating signals for actuating elements of the grippers are generated.Type: GrantFiled: December 14, 2012Date of Patent: August 16, 2016Assignee: Mueller Martini Holding AGInventors: Stephan Fritsch, Steffen Hoffmann, Falk Preuss

Publication number: 20130043180Abstract: A filtration device designed for the purpose of recovering filtrate from wastewaters is characterized by a rotor system (2) that is drivable in rotary manner about a horizontal axis (5) in a liquid bath in a receptacle (1), and which serves as the support for multiple assemblies (17) of filter discs, the interior spaces of which are connected to the suction side of a pump (39) via a collection chamber (29). The liquid to be filtered is transported with the aid of a pump (40) that is connected to a plurality of distributor lances (35) that extend parallel to and close to the hollow shaft (21) that supports the rotor system (2) via a line (31) with the interposition of a prefilter (41) that is intended to separate a coarse fraction.Type: ApplicationFiled: March 31, 2011Publication date: February 21, 2013Applicant: A.

Publication number: 20130037475Abstract: A filtration device consists of a rotor system (2) which is mounted so that it can be driven to rotate about a horizontal axis (5) in a basin (1) containing a liquid bath, said rotor system consisting of three arrangements (15), for example, each comprising a filter disk pushed onto the tubular cylinder (17) parallel to the axis (5) and therefore being eccentric. The tubular cylinders (17) are fixedly connected to a hollow shaft (18) extending in the direction of the axis (5) for supporting the rotor system (2), this hollow shaft being supported on both ends in bearing units (6, 7) designed as friction bearings which permit a three-dimensional equalization of angle deviations of the axis of the hollow shaft (18).Type: ApplicationFiled: March 31, 2011Publication date: February 14, 2013Applicant: A.

Patent number: 7621708Abstract: An apparatus for pressing a cover onto a printing material block that is moved in a transport direction has a first pressing element that can be moved in a first direction and one or more second pressing element that can be moved transversely to the first direction. The first pressing element, in particular, is a pressing table moving in the vertical direction and the second pressing element one or two pressing rail(s) that can be moved in the horizontal direction. The apparatus has a drive unit, in particular with a servo motor, to which a variable control profile can be applied via a connection to a control unit. The variable control profile allows the movement of the pressing rails, for example their stroke or the course of their stroke, to be adapted to the current processing job. The apparatus is particularly suited for use in adhesive binders.Type: GrantFiled: March 14, 2007Date of Patent: November 24, 2009Assignee: Heidelberger Druckmaschinen AGInventors: Klaus Hampel, Stephan Fritsch, Thorsten Holtmeier, Frank Sommerer, Andreas Steinert
