Abstract: A conveyor belt is provided with at least one guide rim, wherein the guide rim extends in a longitudinal direction of the conveyor belt, such that it enables guiding of the belt along a lateral guide surface on an outer periphery of a roll or the like by which the direction of the belt is changed and by which the belt is subjected to a predetermined bending. The guide rim has a contact surface that is in contact with the conveyor belt. In a position in which the belt is not subjected to any bending in the longitudinal direction thereof, as seen in a cross section cross wise to the longitudinal direction of the guide rim, the guide rim presents residual stresses (σ1, σ2) including an induced tensile stress in opposite lateral regions of the contact surface and an induced compressive stress in a region between the lateral regions. The tensile stress generates a tensile force on the contact surface in a direction away from the conveyor belt and the compressive stress generates a compressive force on the contact surface towards the conveyor belt.

Abstract: A parting tool for the chip removing machining of metal blanks includes a blade and a replaceable cutting insert mounted in a seat, which is delimited between a bottom support and an elastically resilient clamping finger. The cutting insert includes an upper side, in which there is included a front rake surface, as well as an application surface positioned behind the same and against which the clamping finger is pressed. In the clamping finger, a flushing channel is included to spray a cooling medium toward the rake surface. A front nose of the clamping finger facing a shoulder is formed between the rake surface and the application surface and has the purpose of protecting the nose from chips. The shoulder has two knobs mutually separated by a central notch, via which cooling medium can pass from the flushing channel toward the rake surface.

Abstract: A down-the-hole hammer drill bit assembly includes a foot valve and a drill component having respective abutment regions in the form of cooperating lugs and shoulders that may be engaged by rotation of the valve relative to the drill bit component to allow the lugs and shoulders to overlap radially to lock the valve at the drill component. The assembly is advantageous to allow coupling and decoupling on-site without the need for specific swaging or hydraulic/pneumatic assembly tools.
