Abstract: A method for separating a portion of extruded material from the continuous strip leaving an extruder, consisting of passing in front of the extrusion nozzle a withdrawal device associated with at least one cutting member; said withdrawal device and said at least one cutting member are made to move independently of each other with velocities, in the sense of vectors, which differ from each other and differ in relation to the material portion separated.
Abstract: Method for decorating the top of a compression-molded cap of synthetic material intended to close a container, in which the decoration is positioned on a flat support in the form of a disc which is placed in the cavity of the cap forming mold before the constituent material of the cap is introduced, and is found to be bonded to the top of the cap after its removal from the mold.
Abstract: A casting mould made of porous material for forming sanitary appliances, including a plurality of profiled parts which are coupled together to define a casting cavity mould said parts being separable from each other for removing a formed appliance from the mould, means for introducing a slip into the mould cavity at least one insert member cooperating with said mould parts to form at least one undercut region in said appliance, wherein said at least one insert member is associated with one of said mould parts by way of a support unit located inside the casting cavity and comprising two mutually movable members, one of which is fixed and secured to one mould part, and the other movable member supports said at least one insert member and is able to move between a first, casting position in which it arranges said at least one insert member in the configuration which enables it to shape said at least one undercut region, and a second, removal position in which it disengages said at least one insert member from sa
