Abstract: A housing for a laser processing machine is described to treat work pieces. The housing comprises a dividing wall, which separates a first work space having a first length and a second work space having a second length from one another, a first entrance to allow access to the first work space, a second entrance to allow access to the second work space, a closing device, which is configured to selectively open and close the first entrance and the second entrance and a control unit, which is operatively connected to the closing device. The dividing wall is placeable in an operating position, which is variable among at least a first position, a second position and a third position. The control unit is configured to control the closing device as a function of the operating position of the dividing wall.

Abstract: A housing for a laser processing machine is described comprising a dividing wall, which separates a first work space and a second work space, and a covering device, which is configured to selectively cover at least one between the first work space and the second work space. The covering device comprises at least a cover, which is controllable in an active configuration, in which the cover is configured to cover one between the first work space and the second work space and a guide system, which is configured to guide the cover so that the cover, when it is in the active configuration, comprises at least a main portion and an auxiliary portion extending from the main portion and being inclined relative to the main portion.

Abstract: The machine comprises a working apparatus arranged to carry out the working operation on a tube, or a similar blank, and a tube feeding device arranged to feed the tube towards the working apparatus. The working apparatus and the tube feeding device comprise respective clamping members for clamping the tube being worked. According to the invention, at least one of the clamping members of the working apparatus or of the tube feeding device is provided with a displacement sensor arranged to detect and measure any movements of the tube relative to said clamping member while the tube is clamped by said clamping member during the working operation.

Abstract: The machine comprises: a working head carrying appropriate working tools to perform one or more working operations on a tube; a feeding unit for feeding the tube along its longitudinal axis towards the working head; a programmable control unit for controlling the feeding unit and the working head; and an optical sensor arranged to optically measure the forward displacement of the tube being worked along its longitudinal axis and/or the rotational displacement of the tube being worked about its longitudinal axis.

Abstract: A method urges a blank along an axial direction between a movable bending tool and a stationary counter-tool and, while the blank is being moved forwards, of moving the bending tool from a neutral position, in which the blank is not bent, to a working position, in which the blank is bent to the desired bending centerline radius, the working position being rotated with respect to the neutral position by a given angle of rotation depending on the desired bending centerline radius. The method further includes urging the blank between a pair of shoes upstream of the bending tool so as to make the deformation of the blank easier, and the step of moving the bending tool from the neutral position to the working position is carried out by controlling at least two degrees of freedom of the movement of the bending tool in the plane defined by the axial direction and by a transverse direction perpendicular to the axial direction.
