A ball valve (10), in particular for sanitary systems and heating/cooling systems, has a valve body (11) in which a ball shutter (15) equipped with a hollow stem (17) is housed and can be moved in rotation between an open and a closed position of the valve, a hollow control device (32) with a through hole arranged externally and bound in rotation to the stem (17) to move the ball shutter (15) between the open and closed positions, a filter (23) housed in the ball shutter (15), suitable for filtering the fluid in the open position, and removable through the control device (32), a cap (42) for closing the ball shutter (15), wherein the cap (42) is bound to the filter (23) and screw-coupled with the stem (17) of the ball shutter (15) so that the direction of unscrewing of the closing cap (42) corresponds to the direction of rotation of the shutter (15) and of the control unit (32) from the open to the closed position. A ball valve is thus realised which allows easy and safe removal of the filter for cleaning it in any valve installation space.

A strapping head (1) is disclosed that is configured to wind and tighten a strip-shaped element around a load, the strapping head (1) comprising a containing casing (2) defining at least one chamber that is suitable for containing operating components of the strapping head (1) configured to perform at least: - one winding and tensioning step for winding and tensioning said strip-shaped element around the load, - one cutting step for cutting the strip-shaped element and - one immobilizing step for immobilizing opposite ends of the strip-shaped element so as to form at least one closed loop around the load. At least one through opening (3) arranged for connecting fluidly said at least one chamber to the outside environment is obtained in said containing casing (2). The strapping head (1) further comprises: - blowing means (6) arranged for drawing a fluid to be pressurized from outside the containing casing (2) and sending the fluid to be pressurized to the at least one chamber in the form of a flow of pressurized fluid having a pressure greater than that outside said containment casing (2), the blowing means (6) comprising an inlet (7) for the fluid to be pressurized and an outlet for the flow of pressurized fluid; and - supplying means (9) arranged for placing said blowing means (6) in fluid connection with the containing casing (2) to convey the flow of pressurized fluid from the blowing means (6) to inside the at least one chamber so that by traversing the at least one chamber and exiting the through opening (3) the fluid removes powder material present in the at least one chamber, expels the powder material outside the casing (2) and/or prevents powder material entering the at least one chamber from outside. A strapping apparatus, a wrapping apparatus and a strapping method are further disclosed.

A support device for supporting workpieces and a machining center including said support device are described, wherein two or more support bars are arranged above a horizontal worktable parallel to one another and are slidably coupled to guiding means with the ability to perform transverse movements so that they can be approached and moved away from one another, each support bar carrying two or more movable suction cup locking devices with the ability to slide along a longitudinal axis of the respective support bar, each locking device comprising an upper end engageable with the workpiece and a lower end engageable with the worktable, blowing means configured to generate an air cushion at the lower end of each locking device to facilitate its movement on the worktable.

A method and a numerically controlled machining center for processing sheets are disclosed, in which a large sheet is positioned on locking devices arranged on a work surface of the machining center and is then cut with a cutting tool to obtain two or more sheet portions, and in which a numerically controlled manipulator laterally moves at least one sheet portion that adheres by suction to at least one underlying locking device that slides on the work surface supported by an air cushion until it stops the sheet portion, interrupting the air cushion and activating a suction that blocks the locking device to the work surface in a desired position in which the sheet portion is further processed by removing material.

A support group (1) is disclosed that is suitable for rotatingly supporting a rotatable resting plate (101) of a rotating table (100) for a wrapping apparatus, the support group (1) being provided with: - a base (2); and with - a plurality of rolling elements (3). The rolling elements (3) are configured to be fitted to the base (2) and to support a lower surface (103) of the resting plate (101) rotating around a vertical axis (Y) of rotation. Each rolling element (3) is freely rotatable around a respective longitudinal axis of rotation (L). Each rolling element (3) has an outer frustoconical contact surface (4) and the longitudinal axis of rotation (L) of each rolling element (3) is arranged on a respective vertical plane passing through the vertical axis (Y) of rotation and is tilted with respect to the lower surface (103) of the resting plate (101) so that the outer frustoconical contact surface (4) abuts on the lower surface (103), so that the peripheral speed of each zone of the outer frustoconical contact surface (4) is equal to the peripheral speed of a respective portion of lower surface (103) that rests on this zone.

A device for cutting a capsule of tethered type for closing a container is disclosed, in which the cutting device comprises a first set of horizontal blades that are coplanar with each other, a second set of horizontal blades that are coplanar with each other and spaced vertically apart from the horizontal blades of the first set, and a set of transverse blades arranged for joining together the horizontal blades so as to make two connecting straps between a tamper-evident band and a side wall of the capsule, in addition to another transverse blade that on one side terminates in an intermediate point of one of the horizontal blades and on the opposite side terminates in a free point, i.e. not adjacent to any blade, so that a transverse notch made by this other transverse blade ends with an end completely surrounded by a portion of capsules that is not destined to be broken.

Provided are an optical imaging device and an optical imaging method, related to the art of optical imaging. The device includes: a first optical path assembly, a second optical path assembly and a transmission structure. The first optical path assembly is fixedly connected to the transmission structure and is configured to move under the driven of the transmission structure. The second optical path assembly is arranged inside the transmission structure and is configured to move under driven of the transmission structure. The first optical path assembly and the second optical path assembly are in optical path connection with each other. A first optical transmission path of the first optical path assembly and a second optical transmission path of the second optical path assembly form an angle. During the movement of the transmission structure, the second optical path assembly remains stationary relative to the first optical path assembly. In the present disclosure, the straight-line optical path structure is disassembled into the folded optical path structure, which effectively utilizes the space inside the transmission structure, and reduces the volume occupied by the optical path assemblies, thereby reducing the overall device volume, size and weight of the optical imaging device, and meeting various requirements for miniaturization.
