20120001370 | PRESSURE ADJUSTMENT DEVICE IN STRETCH BLOW MOULDING MACHINES - A pressure adjustment device applicable in particular, but not exclusively, to stretch blow moulding machines. More particularly, the invention relates to a pressure adjustment device for stretch blow moulding machines of containers made of plastic material. The device includes an opening for dispensing a blowing fluid, a hollow body having a first inlet opening for a high pressure fluid and a second inlet opening for a piloting fluid. A shutter is slidably arranged within the hollow body, the shutter being held in a closed position by elastic means, wherein the adjustable opening of the shutter occurs, in contrast with the elastic means, by introducing—through said second inlet opening—the piloting fluid into a piloting chamber arranged between the hollow body the shutter, and wherein the piloting fluid has a controlled and adjustable pressure. | 01-05-2012 |
20130084354 | OVENS FOR PREFORMS - Ovens for preforms in plastic material, applicable in particular but not exclusively to blowing machines and stretch blowing machines, are provided. | 04-04-2013 |
20130115326 | MACHINES FOR BLOWING OR STRETCH BLOW MOULDING OF BOTTLES - Machines are provided for the blowing or stretch blow moulding of bottles or containers having a plurality of moulding units, each moulding unit having a first half-shell and a second half-shell, laterally hinged around a hinge pin having a hinge axis, and a bottom suitable for cooperating to cyclically form a closed cavity suitable for receiving a pre-heated pre-form and for allowing the expansion by stretch blow moulding of the preform inside the cavity so as to obtain a bottle, said moulding unit being arranged to cyclically assume a closed mould configuration and an open mould configuration by means of opening and closing elements of the half-shells towards and away from a closure plane X-X passing through said hinge axis, and movement elements of the bottom, wherein said half-shells and said bottom are actuated in a synchronized manner stating from a single motion inlet comprising a single cam coupling. | 05-09-2013 |
20130243895 | SYSTEM FOR HANDLING OBJECTS IN ROTARY MACHINES - A system for handling objects in rotary machines, and, more particularly, a system for handling preforms in blowing machines. The system picks up a pre-heated preform from a transferring star of the preform and takes it to a mould of a stretch-blowing machine by using movements entailing reduced acceleration values, in particular of the tangential acceleration component, so as to prevent uncontrolled oscillatory movements of the softened preform. In the blowing machine, the preform is blown to obtain a bottle, and the bottle thus obtained is picked up from the stretch-blow moulding position and transferred to an unloading position. | 09-19-2013 |
20130330437 | SYSTEMS FOR SPACING AND TRANSFERRING OBJECTS BETWEEN OPERATIVE STATIONS - Systems for spacing and transferring objects between operative stations are provided. Such systems can be used with ovens for preforms for plastic material, in blowing or stretch-blowing machines and for other applications in the packaging field. Such systems provide spacing and transferring of objects advancing in procession on transport elements, from a minimum pitch to a preset pitch larger than said minimum pitch, and for transferring said spaced objects to handling elements. | 12-12-2013 |
20140035220 | MACHINE FOR SEPARATING SHEETS OF CARTONS - A sheet separator machine for cartons for packaging from a warehouse, typically a well warehouse, in which the cartons are stacked. More particularly, a machine for separating sheets of cartons. The machine includes a frame on which a handling station of the cartons, a warehouse for at least one stack of cartons, and a gripping station of the cartons, are mounted, in an operatively contiguous position. The gripping station includes a pair of counter-rotating motorized rolls for withdrawing a carton from the stack of cartons. | 02-06-2014 |
20140120203 | HEATING SYSTEM FOR OVEN FOR PREFORMS - The present invention relates to an oven for preforms in plastic material, and particularly to a heating module to be used in said oven. Particularly, the present invention relates to a heating module ( | 05-01-2014 |
