Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
236 words
A moulding machine comprising in combination: a. a mould cavity b. a blank-receiving member, and c. transfer means for transferring a blank of sheet material to the said blank-receiving member, whErein the transfer means comprises means for supporting the blank at a small distance from the blank-receiving member, means for holding a first part of the blank against the blank-receiving member and means for wrapping the remainder of the blank around the member so that the blank assumes the outer peripheral contour of at least part of the member, the wrapping means including a pair of pivoted arms, an end of each of which arms is operatively engageable with the blank, the blank-receiving member being provided with means for securing the blank to the member after the blank has been transferred to the member by the transfer means and the member being arranged to enter the mould cavity of the machine with the transferred blank secured to it; and wherein the holding means is movable to displace the said first part of the supported blank through said distance and into engagement with the blank-receiving member, and each arm is mounted for pivotal movement about a fixed pivot, pivotal movement of the arms bringing the said ends of the arms which engage the blank towards each other whereby the remainder of the blank extending is opposite directions from the said first part gradually engages the blank-receiving member.

Claim 3
Dependent Claim
18 words
Moulding machine as claimed in claim 1 in which the holding means comprises at least one reciprocable finger.
Claim 4
Dependent Claim
15 words
Moulding machine as claimed in claim 1 in which the arms have a common pivot.
Claim 5
Dependent Claim
37 words
Moulding machine as claimed in claim 1 in which the said ends of the arms are straddled by a strip of material which ensures that the blank closely mates with the outer peripheral contour of the member.
Claim 6
Dependent Claim
13 words
Moulding machine as claimed in claim 4 in which the strip is elastic.
Claim 7
Dependent Claim
38 words
Moulding machine as claimed in claim 1 in which each arm is of generally L - shape, the member lying within the angle of the L when the arms have completed transfer of the blank to the member.
Claim 8
Dependent Claim
29 words
Moulding machine as claimed in claim 6 in which the said end of each arm extends inwardly relatively to the limb of the L on which it is provided.
Claim 9
Dependent Claim
31 words
Moulding machine as claimed in claim 1 in which the support means has releasable securing means for holding the ends of the blank in position when the holding means is actuated.
Claim 10
Dependent Claim
31 words
