An apparatus comprises an extruding device having a dispensing opening for extruding a flowable material along an exit direction through the dispensing opening, and a cutting arrangement for separating a dose from the flowable material, the cutting arrangement being movable with a motion component that is parallel to the exit direction.

Apparatus and methods for processing doses of flowable material

An apparatus includes a first mold part suitable for receiving an object, a die arrangement arranged for surrounding a zone of the object and a second mold part cooperating with the die arrangement and with the first mold part in order to compression-mold plastics on the object in the zone.

A above knee prosthesis (P) applied to femoral connection () of an amputee that comprises a upper hinge () connected to femoral connection of the patient, an articulation axis () with the function of reproducing the knee movements, a tibia-calf muscle unit () pivotally connected to the femoral&#x2022;segment and a damper () that reproduces some functions of the calf muscle and ensures to the prosthesis to brake and to allow the sequential swing and stance phases typical of the gait. The damper comprises a cylinder () wherein a piston () and a stem () act connected to each other and adapted to carry out a damping reaction of said damper responsive to the forces loaded on the prosthesis. In particular, a force transducer is provided in the damper arranged, in particular, in the stem with a microprocessor that receives a force signal from the transducer and operates means for adjusting the reaction of the damper responsive to the detected force signal.

Automatic prosthesis for above-knee amputees

An apparatus comprising a transferring element for transferring a dose of flowable material, said dose being provided with an elongated body having a transverse dimension and an end zone, a receiving member for receiving said dose from said transferring element, wherein said transferring element comprising an end-forming arrangement for forming said end zone in such a way as to decrease said transverse dimension in the vicinity of said end zone. A dose of plastics comprises an elongated body provided with a transverse dimension, said elongated body comprising an end zone provided with a respective transverse dimension that is less than said transverse dimension.

Apparatus for transferring doses and dose

Apparatuses and methods for processing doses of flowable material

An apparatus comprises: forming means movable along a first path for compression moulding doses of plastics; a plurality of transfer means for transferring said doses to said forming means; a plurality of arm means, each arm means being associated with a corresponding transfer means for moving said transfer means along a second path having a portion substantially coinciding with a further portion of said first path.

Compression moulding apparatus

An apparatus for forming an object from a dose of plastics comprises a die arrangement provided with a cavity for receiving said dose and with at least two parts that are reciprocally movable for shaping an undercut portion of said object, at least one fluid for applying a clamping force so as to keep said at least two parts in contact; said at least one fluid is such as to increase discontinuously said clamping force from an initial force that is applicable when said dose is substantially contained in said cavity to a final force applicable when said at least two parts shape said undercut portion.

Apparatuses for forming objects with undercut portions

The preform is formed by an upper neck which maintains unchanged its form in the final object and a hollow body, joined to the neck. The method foresees the insertion, within a matrix cavity, of a metered body of polymeric material whose mass is metered according to a reference value, and the subsequent pressure insertion of a punch within the matrix cavity until it closes the mold's molding chamber, the punch conferring the shape to the inner surface of the preform and the matrix having an inner surface which confers the shape to the outer surface of the preform. According to the invention, in the molding of the preform, the error of the mass of the metered body with respect to the reference value is distributed in the hollow body, which undergoes a subsequent hot deformation until it achieves the final shape. In the mold, the matrix comprises at least one deformable wall () whose inner surface defines at least part of the inner surface of the matrix part intended to give form to the hollow body of the preform, said deformable wall () having, at least in part, a relatively thin thickness which permits it to be elastically deformed under the pressure of the polymeric material in the final preform molding step, thereby varying the thickness of the hollow body.

Device for separating and transporting a sized portion of material in a plant for forming articles by compression moulding

Method for forming articles of synthetic material by compression moulding, comprising the following operative stages: inserting a first measured quantity of synthetic material in the plastic state into the cavity of a mould comprising a punch with which it defines a first forming chamber for said measured quantity; pressing said measured quantity to obtain a first portion of the article; opening the mould and inserting a second measured quantity into said cavity; closing the mould by repositioning the punch relative to said cavity to define a second forming chamber; pressing said second measured quantity and again opening the mould, then extracting said article from the punch. The method is implemented by a plant comprising a plurality of forming units (), and at least one device (&#x2033;) for feeding in succession at least two measured quantities () of synthetic material in the plastic state to each of said forming units (), each of said forming units comprising an upper half-mould provided with at least one punch () and a lower half-mould comprising at least one die () provided with a cavity matching said at least one punch (), means being provided to align said at least one die with said at least one punch in succession and to drive said die along the alignment axis, and means which collaborate with said at least one punch and said at least one die in such a manner as to define at least two different forming chambers.
