Title: Method and apparatus for producing casting moulds
IPC: B22C25/00
Filed: 1974-12-11
Abstract: 1482683 Producing casting moulds VON ROLL AG 11 Dec 1974 [13 Dec 1973] 53682/74 Headings B3F and B3G An apparatus for producing casting moulds consists of two separate conveyer loops 1, 2 in which mould assemblies formed from flanks 5, and pattern plates 3 are produced in loop 1, while mould assemblies formed from flanks 5 and loose patterns 10 on bed plates 11 are formed in loop 2. The two loops join to form a common flow path along which is a station S at which mould filling material, e.g. sand is supplied, followed by a compacting station P in which there is a compacting press. The feed mechanism to the carrier path may be selectively interrupted to present either type of mould for filling and compaction, depending on the nut required, thus giving efficient use of the exposure equipment in the system i.e. the said supply and compacting equipment. On leaving the compacting station P, in which the pressure may be varied by control P<SP>1</SP> to suit the particular mould requirements, the pattern plate 3 is removed at station T and the mould passed out of the system to a casting unit. In the case of the loose patterned moulds, the filled mould is separated from the bed plate 11 at section T<SP>1</SP>, the patterns removed at station A, and the mould passed on to the casting unit. In either case, pattern plate 3, bed plate 11 and patterns 10 are recycled through the appropriate part of the system for re-use. In an alternative embodiment, after removal of the bed plate 11 at station T<SP>1</SP>, the mould may be turned out to act as the drag portion of a two-part mould, and recycled through loop 2 to produce a cope, the drag acting as a bed plate. In a further embodiment, Fig. 3 the assembly station F of the pattern plates and of the loose patterns may be common to both loops, with suitable branching conveyers after compaction to enable the alternatives described above to be operated. Yet a further embodiment envisages the loop 1 being even more compact, and extending over two or three vertical levels.

Title: Improvements relating to the production of film
IPC: B29C48/03
Filed: 1965-12-21
Abstract: 1,075,988. Tubular film making apparatus. E. I. DU PONT DE NEMOURS & CO. Dec. 21, 1965 [Dec. 29, 1964], No. 54151/65. Heading B5B. Apparatus of the type used for making biaxially oriented tubular films by the " inflation " process is provided between the extrusion die and the nip rolls for flattening the inflated film with a cylindrical sleeve which is coaxial with the annular extrusion orifice of the die and is flared outwards at the end remote from the die in the form of a truncated cone. As depicted in the drawings (not shown), a molten thermoplastic synthetic organic polymeric material is extruded through the annular extrusion orifice of die 11 in the form of a tubular film 14 which is then drawn over the internally cooled metal mandrel 12 by means of two sets of driven rubber squeeze rolls 13. The mandrel cools the film to a temperature at which it resists stretching. The film is drawn longitudinally by means of a pair of nip rolls 24 rotating at at least twice the peripheral speed of the film advancing rolls 13 and while under drawing tension is advanced through a preheater 18 by means of which it is heated to a temperature which is preferably just below the minimum at which orientation of the film becomes possible. Air or other gas introduced into the film through the inlet 20 and vented through the outlet provides the few inches of water gauge required to inflate and expand the film. The film is heated to a temperature within the orientation temperature range by means of the internal electric radiant heater 22 mounted on the shaft 19. Upon reaching the orientation temperature range the tubular film tends to expand and its outside surface bears against the inner surface of the cylindrical portion 37 of a restraining device 36 of annular crosssection and starts to expand only when it reaches the diverging flange portion 38 which still exerts a degree of restraint and at the same time begins to cool the film. After leaving the restraining device the film expands more without restraint and at the same time its outer surface is cooled by an annular stream of air directed on to it from a cooling ring 31 so arranged that part of the cooling air impinges on the outer surface of the film and part on the cooling fins 35 located on the outer surface of the flange 38. The inflated film is then drawn through a cylindrical cooling member and sizing die 25 of annular cross-section whose walls are cooled internally by passing cooling water through it. The film material may be a polyolefine such as polypropylene.
