Publication number: 20150314171Abstract: The present invention relates to a support cradle (1) for bowling balls (3). Such a support cradle comprises a support surface (2) adapted to a bowling ball and carried by a frame (4). The support cradle also comprises a bottom cup (7) disposed to join the support surface substantially tightly. The support surface adopts a shape that substantially corresponds to the geometry of the spherical surface (8) of the bowling ball (3). In this connection, the support surface and the bowling ball fitted on this are disposed to form together a substantially tight joint. The support cradle also comprises a connection (9) for compressed fluid for introducing said compressed fluid through the connection in the support cradle, the compressed fluid introduced in the support cradle (1) forming a compressed-fluid cushion between the support surface and the bowling ball. In this manner, the bowling ball is allowed to turn in any direction virtually frictionless.Type: ApplicationFiled: December 11, 2013Publication date: November 5, 2015Inventor: Göran HÖGLUND

Publication number: 20150298279Abstract: The present invention relates to a method and an arrangement for grinding spherical products (12), such as e.g. bowling balls, in particular. Such an arrangement comprises at least one grinding machine (1) having a spherically oscillating grinding movement. A fastening plate (6) fitted on the grinding machine has a spherically shaped bearing surface (7) and a grinding product (9) fitted on this, which through its slits (13) adopts a position with accuracy of shape on the spherically shaped surface. The grinding product (9) will form a contact surface (17) in the interface, in which the grinding product cooperates with the spherical product. This contact surface then adopts a radius of curvature arranged to substantially correspond to the radius (r) of the spherical product (12). The grinding is performed with a spherically oscillating grinding movement, which is adapted to the radius of the spherical product and simultaneously coincides with the radius of curvature of the contact surface.Type: ApplicationFiled: November 28, 2013Publication date: October 22, 2015Inventor: Goran HÖGLUND

Patent number: 8795036Abstract: The present invention relates to a method for manufacturing a flexible abrasive disc, and to such an abrasive disc. The abrasive disc comprises a backing with an upper side and a lower side. The upper side has an abrasive agent coating for forming a surface layer. In order to form a surface layer as specifically patterned as possible, the backing of each abrasive disc is coated separately. In this manufacturing method, the abrasive agent coating on the upper side of the backing is embossed with an embossing mold specially structured and to be pressed against the backing.Type: GrantFiled: November 21, 2011Date of Patent: August 5, 2014Assignee: Oy Kwh Mirka ABInventor: Goran Hoglund

Patent number: 8216030Abstract: The present invention relates to a flexible grinding product and a method of producing the same. Such a grinding product comprises a flexible underlay (1) which consists of two layers laminated to each other. These comprise a lower base layer (2) and an upper layer (3), a cavity layer. The underlay includes a top surface (5) having at least one adhesive layer (6) arranged thereto after lamination and a layer of grinding agent (7) applied by means of the adhesive layer. The grinding product is characterized in that the layer that is coated with grinding agent includes holes which form cavities (4), whereby the cavities provide space for grinding dust and grinding residues and facilitate their removal from the surface being ground.Type: GrantFiled: December 22, 2011Date of Patent: July 10, 2012Assignee: Oy KWH Mirka ABInventor: Goran Hoglund

Patent number: 7789731Abstract: The present invention relates particularly to an oscillating grinding machine. The grinding machine comprises a driving motor (3) surrounded by a body (3), and a drive shaft (4) cooperating with the driving motor. The drive shaft comprises a grinding head (5) that constitutes a support for a grinding product (8). The drive shaft (4) is arranged in two pieces and comprises a main shaft (11) and an eccentric shaft (10) arranged rigidly thereto. The eccentric shaft comprises a center line (12) that assumes an angle (?) against a corresponding center line (13) of the main shaft, and thus the grinding head (5) will assume an eccentric placement in relation to the main shaft (11). Thus, the grinding head is arranged to oscillate in a substantially spherical plane provided by the rotation of the main shaft and the eccentricity and inclination of the eccentric shaft in relation to the main shaft.Type: GrantFiled: October 31, 2008Date of Patent: September 7, 2010Assignee: OY KWH Mirka ABInventor: Goran Hoglund

Publication number: 20070293131Abstract: The present invention relates to a method for manufacturing a flexible abrasive product, to such an abrasive product as well as to an apparatus for manufacturing the same. Hereby, the abrasive product is formed to be of the shape of a substantially regular polygon by die cutting it off a material strip. In the present case, the abrasive product has obtained a polygonal shape in which adjacent sides have a reciprocal interior angle of substantially 120 to 150°, whereby the die cutting is carried out in such a way that it coincides at least partly with the die cutting of several adjacent abrasive products. In this way, the die cutting can provide a partially continuous cutting line on the periphery of each individual abrasive product, which cutting line has a significant part of its length in common with the adjacent abrasive products.Type: ApplicationFiled: June 14, 2007Publication date: December 20, 2007Applicant: Oy KWH Mirka AbInventor: Goran Hoglund
