摘要:
An apparatus for making a fracture cut between the cup and the safety ring in plastic caps, which comprises rotary means (11) provided with at least one mandrel (12) that can be arranged inside the cup (3) and is suitable to produce the rolling, about its own axis of symmetry (S), of the side wall (13) of the cup (3) along the cutting edge (14) of a blade (15) for making the cut, the blade (15) being associated with an inlet path portion (16) adapted to axially offset the cup (3) with respect to the rotation axis (R) of the mandrel (12) by clamping the side wall (13 ) against the mandrel (12); the apparatus also comprises means (17) for recentering the cup (3) with respect to the rotation axis (R).
摘要:
A support for the decorative printing of surfaces (2) is described, having a plate-like silicone structure on one face (3) of which is distributed a colouring substance to be transferred onto said surface (2), and comprising a reinforcing structure (6) at least partially embedded in the plate-like structure.
摘要:
An apparatus comprises transfer means (4) rotatable at a speed (v) to transfer a dose of plastics from supply means (2; 2a; 2b) to forming means (5) of said dose, control means that is suitable for varying said speed (v) in a substantially continuous manner between a minimum value and a maximum value being associated with said transfer means (4).
摘要:
A mould comprises at least two die parts (2), each die part (2) comprising a recess (71) for forming a portion of an object and conduit means (4) through which a cooling fluid can flow, said conduit means (4) comprising a curved conduit (43) which surrounds said recess (71), an inlet conduit (41) having a supply portion (41a) which leads into said curved conduit (43) and an outlet conduit (42) having a discharge portion (42a) which leaves said curved conduit (43) so as to define a path for said cooling fluid, said curved conduit (43) , said supply portion (41a) and said discharge portion (42a) being arranged sp as to be interceptable by a common plane (40) that contains said path.
摘要:
A plant for controlling powder granulometry, comprising a distribution plane (3) destined to receive a layer of powders and means (4) for detecting designed for acquiring at least an image of the layer of powders, a light source (8) being associated to the means for detecting, the light source being located, with respect to the distribution plane, opposite a position of the means for detecting, and being destined to direct a light beam towards the powders of the layer of powders.
摘要:
A process for the functional regeneration of the porosity of the materials used to make moulds (2) for moulding ceramic objects, when the pores have been damaged by use of the mould (2), comprises the sequential execution of at least two successive steps of an ordered sequence which includes the steps of: eliminating contamination caused by organic substances from the mould (2); eliminating contamination of biological origin from the mould (2); attacking inorganic encrustations and eliminating inorganic substances which have infiltrated the pores of the mould (2), the initial step of the process being preset according to the nature of a predetermined contaminating agent.
摘要:
A method and a machine for the decorative printing of surfaces, particularly of tiles and the like, are described and in which is provided for a colouring substance to be transferred onto a surface (2) to be decorated through a mask (21) on which the colouring substance is distributed, the colouring substance being transferred onto the surface (2) by the action of a jet of gas directed onto the mask (21).
