Abstract: A method for manual casting of polymers, is used for production of a molded part. The production of the molded part comprises providing a mold with a cavity, preparing a liquid polymer according to a recipe, manually casting the liquid polymer into the mold and solidifying the liquid polymer in the mold resulting in the molded part. A system comprises the mold and at least one sensor Wherein the system uses parameter data to calculate the recipe. The system comprises an electronic device and a display, wherein the electronic device controls the display. The display shows during the production of the molded part at least a part of at least one production step of the recipe.

Abstract: The invention relates to an arrangement (200) comprising a storage tank (100), a heating device (1) configured to heat the storage tank (100), said heating device (1) comprising: a casing (10) defining an internal volume, said internal volume having a main chamber (14), said storage tank (100) being arranged at least partially in the main chamber (14), a heating element (20) arranged in the internal volume, a blower (30) configured to create a flow by sucking gaseous fluid from at least the upper part (10a) and to deliver sucked gaseous fluid in the main chamber (14); wherein a suction duct (40) extends in the internal volume, the blower fan (30) being arranged in said suction duct (40), characterized in that the arrangement (200) further comprises a guiding sleeve element (50) arranged in the main chamber (14) forming a peripheral space (51) around the storage tank (100) in order to speed up the flow and optimize the heat transfer(100).

Abstract: The invention relates to a manufacturing method and a dispensing machine comprising a metering step and particularly a calibration of mass flow of each component, which is completely automatically implemented. Therefore, said dispensing machine of the invention guarantees a reliable calibration, free of operational or input error and is saving operator time.

Abstract: A device for unstacking flat objects comprises an unstacking head (2) provided with a suction cup (88) for grasping the first flat object in a stack of such objects presented thereto and for moving a grasped flat object towards an exit position (40) in which the object is released. The suction cup (88) is a bellows suction cup made of a flexible material such that when it grasps the first flat object in the stack, it retracts under the effect of the suction and entrains at least the surface of the grasped object therewith as it retracts. A shoe (90) having a surface close to the grasping plane of the suction cup is disposed adjacent to the suction cup in fixed relationship relative to the mount (50) carrying the suction cup. The shoe thus constitutes an obstacle to the surface of a grasped flat object, thereby warping said surface as the suction cup retracts.

Abstract: A method of extracting and accelerating flat objects such as postal items which are presented in the outlet position of an unstacking head for use by a machine downstream therefrom, the method making use of a clamp for grasping postal items one-by-one and of various sensors (7) such as photoelectric cells, serving to indicate the presence of a postal item in the outlet position of the unstacking head, or in the field of action of the clamp, or serving to indicate that the clamp is in a waiting position or in an end-of-stroke position, the method being characterized in that it essentially comprises the following stages:moving the clamp to a waiting position;when the presence of a postal item is expected in the outlet position from the unstacking head, driving the carriage towards the outlet position of the unstacking head;when the presence of the postal item is detected within the field of action of the clamp, the clamp is closed and the carriage is driven towards the downstream machine;as soon as the presence

Abstract: A holder for selectively manipulating small format flat objects and large format flat objects comprises a support assembly adapted to pivot between two stable positions. This assembly is formed by first and second members attached perpendicularly to respective opposite sides of a third member. The first and third members form an L-shaped support for large format objects in one of the two stable positions. The second and third members form a T-shaped assembly. A base has an inclined end portion on which the support assembly is pivotally mounted at a point between the second member and the point at which the first member and the second member are attached together. As a result, the support assembly pivots about an axis which is substantially coincident with the intersection of the second and third members. A first of the two stable positions is defined by an abutting relationship between the inclined end portion of the base and the second member.

Abstract: An unstacking device for objects such as mail envelopes is of the type comprising a magazine for storing and feeding stacked objects and a discharge head for separately removing jogged objects from a stack. The device is provided within the terminal portion of the magazine with a transition edge guide which serves to restore inclined objects to a practically upright position for subsequent discharge and is inclined with respect to the direction of feed motion of stacked objects and with a jogging reference edge guide which is relatively displaced towards the exterior of the magazine. There are associated with the edge guides a feed screw for advancing objects and a delay screw for retarding objects, the screws being interposed between jogging rollers opposite to the edge guides.
