  • Publication number: 20080001344
    Abstract: A feeding device is provided for feeding a material to be processed to a working unit present in a sheet processing line. The feeding device includes a frame element which is provided with a gripping device configured to grip the material to be processed for setting off a feeding motion. The gripping device include a transfer element, which is provided with a press member engageable with one surface of the material to be processed, with the press member being located substantially in coincidence with the center line of the material to be processed. The press member is configured to move in lateral direction along with the material to be processed.

  • Patent number: 6526800
    Abstract: A sheet fabrication machine is equipped with different servo motors for actuating its upper tool and its lower die. A direction converting mechanism is provided to each of the tool assembly and the die assembly so as to convert the non-vertical forces output by the servo motors into vertical forces that enable the tool and die to move relative to each other to effect work on a workpiece placed therebetween. The sheet fabrication machine is moreover equipped with a system and logic for automatically measuring the length of the tool and for providing a setting from which the operation of the tool can be referenced. Additional features provisioned into the sheet fabrication machine include look ahead functions for optimizing the operational speed of the machine while minimizing the noise generated as a result of the operation.

  • Patent number: 6101863
    Abstract: The working machine comprises a first (ET) and a second (TT) machining means, at least the first one (ET) being arranged to move in relation to the machine body (28) towards the second one (TT), to accomplish machining of a sheet material, wherein the sheet material to be worked is placed between the machining means (ET) and (TT). At least one of the machining means (ET and TT) is provided with means (7, 9) for conducting the transfer and working movements of said tool (ET, TT). The first part (7) of the means is fixed to the machining means (ET, TT), and the second part (9) of the means is fixed to the machine body (28), to be movable in relation thereto by actuators (10, 11, 14-26, 39, 41) in the machine body (28). The movement of the second part (9) of the means (7, 9) in relation to the machine body (28) during machining based on pressing of the sheet material is transmitted from the second part (9) to the first part (7) by a contact surface connection.

  • Patent number: 6021658
    Abstract: The invention relates to a sheet fabrication machine that machines worksheets. The body of the machine includes first and second machining tool mechanisms at least one of which being arranged to move in relation to the machine body towards the other to machine a worksheet placed between the machining tools. At least one of the machining tool mechanisms is provided with a contact mechanism that conducts the transfer and working movements of the tool. One part of the contact mechanism is configured to have at least one guide surface part formed as a beveled surface in relation to the direction of movement of the machining tool. A contact surface connection between a first part and a second part of the contact mechanism in relation to the guide surface part defines the position of the machining tool.
