Patent number: 11173540Abstract: The moulding machine includes a moulding chamber having at least one chamber end wall provided with a pattern plate adapted to form a pattern in a mould part and associated with a reference pattern block positioned in fixed relationship to a pattern of said pattern plate and adapted to form a reference pattern in an external face of a mould part. A detection system detects the position of a pattern face of the reference pattern of the sand mould part. A transverse and/or a rotational compaction position of a pattern plate is adjustable by means of at least one actuator. Said actuators are controlled by means of a control system on the basis of successive position detections performed by the detection system of pattern faces of reference patterns of compacted sand mould parts traveling along said path of travel.Type: GrantFiled: January 13, 2021Date of Patent: November 16, 2021Assignee: DISA INDUSTRIES A/SInventors: Per Larsen, Christoffer Bay, Jørn Johansen, Christian Dam, Flemming Floro Hagemann

Patent number: 10919087Abstract: The moulding machine includes a moulding chamber having at least one chamber end wall (8) provided with a pattern plate adapted to form a pattern in a mould part and associated with a reference pattern block positioned in fixed relationship to a pattern of said pattern plate and adapted to form a reference pattern in an external face of a mould part. A detection system detects the position of a pattern face of the reference pattern of the sand mould part. A transverse and/or a rotational compaction position of a pattern plate is adjustable by means of at least one actuator (91, 92, 119). Said actuators are controlled by means of a control system on the basis of successive position detections performed by the detection system of pattern faces of reference patterns of compacted sand mould parts travelling along said path of travel.Type: GrantFiled: December 4, 2017Date of Patent: February 16, 2021Assignee: DISA INDUSTRIES A/SInventors: Per Larsen, Christoffer Bay, Jørn Johansen, Christian Dam, Flemming Floro Hagemann

Patent number: 10589348Abstract: The moulding machine includes a moulding chamber having at least one chamber end wall provided with a pattern plate adapted to form a pattern in a mould part and associated with a reference pattern block positioned in fixed relationship to a pattern of said pattern plate and adapted to form a reference pattern in an external face of a mould part. The reference pattern block includes a face having a tangent varying in a longitudinal direction of the moulding chamber and being adapted to form a corresponding reference pattern in the sand mould part. A non-contact detection system (87) detects the position of a number of different points (P1, P2) distributed over the pattern face of the reference pattern in the longitudinal direction of the sand mould part, and the tangent (T1, T2) in the longitudinal direction of the sand mould part is different between at least two of said points.Type: GrantFiled: June 4, 2015Date of Patent: March 17, 2020Assignee: DISA INDUSTRIES A/SInventors: Per Larsen, Christoffer Bay, Jørn Johansen, Christian Dam, Flemming Floro Hagemann

Patent number: 6511572Abstract: The invention relates to a method of forming cutouts (4) and transverse welding seams (10) in a sheet of film (5) that is advanced continuously at high velocity, wherein the cutouts (4) constitute areas that are delimited by cutting lines (6, 7), wherein the method comprises the following steps: a) the formation of the cutouts (4) in a sheet section with high sheet tension with cutting lines (7) that extend longitudinally of the sheet of film (5), and cutting lines (7) that extend transversely of the sheet of film, said cutting lines featuring a number of interruptions (8) that constitute support points whereby the cutouts (4) continue to be coherent with the sheet of film (5) at the support points, b) subsequent formation of the transverse welding seams (10) in a sheet section with low sheet tension.Type: GrantFiled: July 10, 2001Date of Patent: January 28, 2003Assignee: Roll-O-Matic A/SInventors: John Buk Jensen, Jens Peder Rasmussen, Christian Dam, Christian Bøg Jørgensen
