摘要:
The unit operates by coupling together under pressure a punch (11) and a die with its closed cavity loaded with a charge of polymer material, the charge being produced outside the die and then inserted into the die cavity. The unit comprises a mould having a lower die part arranged to form the lower part of the outer surface of the article, the inner surface (30a) of which comprises a lower end portion and an axially extending lateral portion. The lower die part (30) comprises a first constituent member (31) and a second constituent member (32) having inner surfaces (33, 34) which can be complementarily aligned to together define the inner surface (30a) of the lower die part (30); the inner surface (34) of the second constituent member (32) defines totally or to a large extend said lower end portion of the inner surface of the lower die part (30). The second constituent member (32) is movable relative to the first constituent member (31) between an upper position in which its inner surface (34) is in said position aligned with the inner surface (33) and a withdrawn position in which its inner surface (34) lies spaced from the inner surface (33) in order to increase the volume of the cavity of the lower die part (30).

A cap comprises a cup body (2) with which a tamper-evident ring is associated (9; 109; 209; 309; 409) delimited by side wall means (15) provided with a connecting zone (16) with which retaining means is connected (17) suitable for engaging with a collar (32) of a container, said side wall means (15) comprising a wall portion (21; 121; 221; 321) that projects towards the outside of said tamper-evident ring (9; 109; 209; 309; 409), such as to enable said connecting zone (16) to expand radially whilst said cap (1) is applied to said container; the disclosure also includes a cap comprises a cup body (2) with which a first edge (13) of a tamper-evident ring (9; 109; 209; 309; 409) is associated, said tamper-evident ring (9; 109; 209; 309; 409) comprising a connecting zone (16) from which flap means (17) extends suitable for engaging with a collar (31) of a container and a second edge (14) opposite said first edge (13), said second edge (14) being joined to said connecting zone (16) by a surface (30) tilted towards the inside of said cup body (2).
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.

An apparatus comprises forming means (2, 3; 102, 103; 202, 203; 302, 303) closable in a direction (A) to form an object (4; 39; 104; 204), said forming means (2, 3; 102, 103; 202, 203; 302, 303) comprising at least two elements (7; 107; 207; 307) reciprocably movable along respective arched trajectories to disengage from said object (4; 39; 104; 204), said arched trajectories having respective components parallel to said direction (A).
摘要:
Described is a method for reconditioning a tool (1) made of porous material or sponge used to machine sanitaryware (2) or the like, especially ceramic sanitaryware (2), that undergoes finishing processes in a working area (3) of a production plant (4) equipped with a robotic unit (5) for processing the sanitaryware (2). The method comprises at least the following steps: moving the sponge (1), which has the shape of a solid of revolution, from the working area (3) to a non-working sponge (1) reconditioning area (6); rotating the sponge (1) about its axis (Z) using related drive means (7); spraying a cleaning/rinsing liquid on the sponge (1); and squeezing the sponge (1) using rotatable pressure means (8) simultaneously along a plurality of lines substantially transversal to the axis (Z) of the sponge (1) and spaced from each other. The invention also relates to an apparatus that implements this method.
摘要:
Machine for forming caps by compression molding comprising: a first carousel (1) rotating about a central axis (2) and provided peripherally with a plurality of compression molding units (3) mounted equidistant from each other and from the axis of rotation; a second carousel (4) rotating about a central axis parallel to that of the first carousel and provided peripherally with means (42) for feeding the charge of material to be molded to die cavities (320) of the first carousel, and means for collecting the molded caps abandoned from punches of the first carousel; a possible third carousel (5) provided peripherally with means for guiding and conveying the caps abandoned by the second carousel; at least one further second carousel (4) associated both with respective means for feeding the material to be molded and with a possible further third carousel (5), such as to form a system having at least two carousels (4) distributed angularly equidistant external to the first carousel (1), so that each mould implements at least two forming cycles for each revolution of the carousel, the two cycles being effected along travel arcs the first carousel which are at least partly superposed.
摘要:
The element has at least one porous permeable impression surface, on which the clay slip is deposited. A drainage system for the slip fluid is provided having a relatively thin, empty or porous chamber in the form of a slab which is incorporated into the body of the mould element itself, is disposed within the range of drainage action of the impression surface, and has a degree of porosity greater than the front part of the body delimited between said thin chamber and the impression surface, evacuation means connected to said thin chamber being provided to evacuate the drained fluid collected by the chamber. In particular, said thin chamber is disposed substantially parallel to the impression surface at a relatively short distance therefrom.
