Abstract
Abstract Apparatus for moulding confectionery, comprising a series of moulds, each of which is divided into a fixed half and a hinged half which is normally aligned with the fixed half, a conveyor for traversing the moulds in sequence past a filling station, through a cooling zone to a discharge station and back to the filling station, a depositor at the filling station which is arranged to deposit different materials into moulding cavities in each half of each mould, mechanism disposed at a folding station beyond the cooling zone for folding the hinged half of each mould about its hinge against the fixed half and effecting deposition of the contents of the moulding cavities thereof into the moulding cavities of the fixed half, mechanism disposed at a following unfolding station for returning the folded hinged half of each mould into alignment with its fixed half, and means for inverting the moulds prior to arrival at the discharge station and turning them right way up during their return to the filling station.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
190 words
Apparatus for moulding confectionery, comprising an endless conveyor, a series of moulds, each of which is divided into a first half attached to the conveyor and a second half which is hinged to and normally aligned with the first half, said conveyor carrying the moulds in sequence past a filling station, through a cooling zone to a folding station, then to an unfolding station and then to a discharge station and back to the filling station, a depositor at the filling station which is arranged to deposit different materials into moulding cavities in each half of each mould, mechanism disposed at the folding station for folding the second half of each mould about its hinge against the first half and effecting deposition of the contents of the moulding cavities thereof into the moulding cavities of the first half, mechanism disposed at the unfolding station for returning the folded second half of each mould into alignment with its first half, and means for inverting the moulds prior to arrival at the discharge station and turning them to cause their moulding cavities to face upwardly during their return to the filling station.
Claim 2
Dependent Claim

Apparatus for moulding confectionery, comprising an endless conveyor, a series of moulds, each of which is divided into a first half attached to the conveyor and a second half which is hinged to and normally aligned with the first half, said conveyor carrying the moulds in sequence past a filling station, through a cooling zone to a folding station, then to an unfolding station and then to a discharge station and back to the filling station, a depositor at the filling station which is arranged to deposit different materials into moulding cavities in each half of each mould, mechanism disposed at the folding station for folding the second half of each mould about its hinge against the first half and effecting deposition of the contents of the moulding cavities thereof into the moulding cavities of the first half, mechanism disposed at the unfolding station for returning the folded second half of each mould into alignment with its first half, and means for inverting the moulds prior to arrival at the discharge station and turning them to cause their moulding cavities to face upwardly during their return to the filling station.
Claim 3
Dependent Claim
56 words
Apparatus according to claim 1, which includes a further depositor situated between the unfolding station and the discharge station and arranged to deposit a third material into the moulding cavities of the fixed halves only of the moulds, and in which the moulds are arranged to traverse the cooling zone again after leaving the further depositor.
Claim 4
Dependent Claim
38 words
Apparatus according to claim 1, which includes a further depositor situated between the cooling zone and the folding station and arranged to deposit a third material into the moulding cavities of the fixed halves only of the moulds.
Claim 5
Dependent Claim
52 words
Apparatus according to claim 1, in which each mould includes a framework attached at its ends to parallel conveyor chains and carrying at its ends rollers which run on supporting rails, the framework having a recess for accommodation of the second mould half in a position aligned with the first mould half.
Claim 6
Dependent Claim
83 words
Apparatus according to claim 4, in which the second half of each mould carries, at the end remote from the first half, a roller which projects from the framework and which includes, both at the folding station and at the unfolding station, a lifting rail which coacts with the rollers on the second mould halves to raise said mould halves to a vertical position followed by a lowering rail which coacts with the rollers to guide said mould halves into a horizontal position.
Claim 7
Dependent Claim
70 words
Apparatus according to claim 5, in which the framework of each mould carries a pivoted latch which is biased to engage a projection on the second mould half to latch it in its position aligned with the first mould half and which includes at the folding station a cam rail which cooperates with the latches to move them clear of the projections and so to permit folding of the moulds.
