Embossing method and apparatus
A method of embossing a crown cap comprises the steps of: detecting a pre-printed drawing on the bottom of the crown cap, varying the angular positioning of the crown cap so as to position the drawing according to a preset positioning, and impressing a raised/recessed pictogram on the bottom of the crown cap. The pre-printed drawing and the embossed pictogram will have a desired reciprocal position.

SEAL SYSTEM FOR MELTED PLASTICS
A seal system includes a male body and a female body that are slidable in relation to one another in an axial direction and between which an interstice is arranged. Plastics in pasty state pass through the interstice to a chamber partially defined by at least one of the aforementioned bodies. An elastic strip is arranged in the interstice to prevent leakage of the plastics.
HOT MELT SYSTEMS, FEEDER DEVICES AND METHODS FOR MOVING PARTICULATE HOT MELT ADHESIVE
Systems, feeder devices and methods are disclosed for moving particulate hot melt adhesive from an adhesive supply to an adhesive melter. A hot melt adhesive system includes a melter configured to heat and melt particulate hot melt adhesive into liquid hot melt adhesive, an adhesive supply containing a bulk quantity of particulate hot melt adhesive, and a feeder device configured to intermittently transfer some of the bulk quantity of particulate hot melt adhesive from the adhesive supply to the melter. An adhesive supply includes a body containing a bulk quantity of particulate hot melt adhesive, and a feeder device integrated into the body and including a mechanical agitator configured to encourage movement of the particulate hot melt adhesive through the feeder device.
Method and apparatus for producing a dispensing part of a container, and dispensing part of a container
A method comprises in sequence the steps of: dispensing a continuous polymeric extrudate in a molten state; separating from the continuous extrudate a dose substantially having the shape of a parallelepiped, the dose having a separation surface at which the dose has been separated from the continuous extrudate, the dose further having a face adjacent to the separation surface; conveying the dose towards a mould comprising a first mould part and a second mould part; shaping the dose in the mould by moving the first mould part and the second mould part one towards the other in a moulding direction arranged transversally to said face, thereby obtaining a dispensing part of a container. The dispensing part comprises: an edge zone suitable for being joined to a container body; a neck surrounding a passage through which a product contained in the container can be dispensed; a membrane which closes the passage, the passage being intended to be opened after the shaping step, so that said product can flow out.
System for feeding molten resin and method of feeding molten resin
To efficiently feed a molten resin to the resin holders. An intermittently feeding device works to intermittently feed a transfer unit equipped with resin holders, and has a cam supported by a motor via a support. The cam is rotated by the motor. A cam follower of a moving block meshes with the screw of the cam, and the moving block moves along a support rail accompanying the turn of the cam. The motor rotates at a constant speed, and the transfer unit 3 is fed intermittently depending on the shapes of the cam and of the cam follower.
APPARATUS AND METHOD FOR COMPRESSION MOULDING CONCAVE OBJECTS
An apparatus that includes a dispensing device for dispensing doses of polymeric material suitable for compression moulding; a mould for receiving doses and making concave objects; a plurality of transport elements of respective doses for releasing doses to the mould; and a carousel for supporting the transport elements for feeding each element in an advancement direction (A) and along a closed path between the dispensing device and the mould. The transport element includes a wall for engaging the dose rotatably mounted on the carousel between a picking up condition and a condition for releasing the dose such that the wall is overturned with a contact surface facing the mould for releasing the dose in the mould by gravity; and wherein it includes cooling means of each transport element for cooling the element at least in a zone of the closed path.
Apparatus for making objects by means of compression moulding
An apparatus for forming an object comprises an extruding device (2) for supplying a continuous extrudate of polymeric material, at least one separating element for cutting the continuous extrudate thereby separating a dose (6; 106) of polymeric material from the continuous extrudate, at least one mould (5; 105; 205; 305; 405) comprising a first mould part (9; 109; 209; 309) and a second mould part (8; 108; 508) which are movable relative to one another between an open position, in which the dose (6; 106) is rested on a receiving part selected from the first mould part (9; 109; 209; 309) and the second mould part (8; 108; 508), and a closed position, in which a forming chamber is defined between the first mould part (9; 109; 209; 309) and the second mould part (8; 108; 508), the forming chamber having a shape corresponding to said object. The apparatus further comprises a thermal conditioning device (11; 111; 211; 311; 411) configured to act on the dose (6; 106) while the dose (6; 106) is positioned in said at least one mould (5; 105; 205; 305; 405) and before the closed position is reached, by thermally conditioning at least one surface portion (20; 120) of the dose (6; 106) which is distinct from a resting portion (17; 117) of the dose (6; 106) which is resting on the receiving part.
