Abstract: A turning roll assembly for the supporting and rotating of a cylindrical object (5) has two pairs of two rollers sets which are axially displaced in relation to each other. A supporting roller of each of the roller sets is rotatably mounted about a horizontal axis (23) in a holder (15,20) which is swivable about an axis (16) situated in a normal plane to the axis of rotation of the object. At least three holders (15,20) are each mounted on its carriage (3). The carriages are freely movable on a foundation in the direction of the axis of the object. The assembly is provided with a mechanism (25,27,29) for each carriage which converts an axial movement of the carriage (3) to a swivel movement of the holder (15,20) about its swivel axis (16). Thereby the foremost end of the roller axis (23) in the direction of movement of carriage swivels backwards in relation to the direction of rotation of the object.
Abstract: A pipe nesting and denesting apparatus is efficiency in transportation of many pipes different in diameters, and said apparatus can operate in a short time nesting work without injuring pipes. Inside the rails of said apparatus, a receiving stand for receiving pipe which is movable up and down is provided, said pipe is moved by a supporting rod on a carriage, and pipes different in diameters are inserted or pulled up on an adjustable nesting stand.
Abstract: A bandsaw mill comprises two vertical bandwheels for receiving and guiding a bandsaw. The bandwheels are mounted on a frame for rotation about horizontally spaced-apart axes. A bridge suspends the frame above the position of a log with the axes of the bandwheels being generally parallel to the longitudinal axis of the log. The log is between the bandwheels. The bandsaw mill includes a mechanism for raising and lowering the frame, a mechanism for moving the bridge longitudinally along the position of the log and clamps for securing the log in a generally horizontal position. A method of sawing the log comprises moving the log into a generally horizontal position, securing the log in the position and moving the horizontally oriented bandsaw in a longitudinal direction along the log to make horizontal cuts along the log.
Abstract: A support installation is provided for use with large, cylindrical loads to provide rotational and longitudinal movement therefor. The support includes a plurality of non-driven all-round rolls and at least one driven all-round roll, the principal rotational axes of the non-driven rolls being parallel to the load and the rotational axis of the driven roll being perpendicular thereto. The rolls engage the circumference of the load for rotational and longitudinal movement. A U-shaped bracket fixedly or yieldably supports the rolls.
Abstract: An extrusion die mounted in a die holder is fitted onto the end of the press stem of an extrusion press by apparatus which has a swing arm which receives a die holder in a first position, then pivots to a second position where the die holder is aligned with the extrusion press stem, rotates the die holder so that it is correctly oriented relative to the press stem and then pushes the die holder axially onto the press stem.
Abstract: A stand for supporting and rotating shafts in fractions of a revolution, for example for assembling armature slot conductors. Conventional arrangements use multiple rollers conforming to the shaft, one of which is motorized by way of gearing. This tends to be cumbersome, expensive and complex. According to this invention a shaft is supported on the walls of a channel between roller stops. A lever within the channel is jacked up to tilt the shaft against one roller and the lever is pushed longitudinally, allowing the shaft to remain in position but rolled around against the stop by an amount corresponding to the linear lever movement. The lever is then lowered and retracted.

Abstract: A fit-up turning roll system suitable for positioning cylindrical workpieces in alignment with other cylindrical workpieces is described. The workpiece rests upon a number of idler wheels which are mounted for free rotation upon eccentric shafts so that by rotation of the individual shafts, the workpiece is re-positioned.
