Abstract
Abstract Apparatus for moulding pie lids and bases comprises a rotary moulding drum with external moulding cavities from which moulded dough pieces are ejected by the application of compressed air internally of the drum, the ejection being assisted by a jet of compressed air directed along the surface of the drum by a fishtail nozzle, and a control system for synchronizing movements of receiving containers with movements of the drum to provide accurate dough depositing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
189 words
Apparatus for molding dough material comprising a movable mold member having at least one molding cavity in its surface, means for filling the cavity with dough material to be molded, means for ejecting the material from the cavity, the filling and ejecting means being operable successively during movement of the movable mold member, container conveying means traveling beneath said movable mold member for conveying containers into a position beneath said mold member to receive the ejected, molded dough material, means for directing a gas stream between said conveyor means and said mold member surface to assist in moving the dough material from the cavity into a container beneath said mold member on said container-conveying means, and control means for synchronizing the movement of containers on the conveyor means with the movement of the mold member so that the ejected molded material will be deposited accurately into a container, said control means comprises container-arresting means and means for releasing the container-arresting means in timed relation with the movement of said movable member so that a container is adapted to pass under the mold member in alignment with a molding cavity.
Claim 2
Dependent Claim
189 words
Apparatus for molding dough material comprising a movable mold member having at least one molding cavity in its surface, means for filling the cavity with dough material to be molded, means for ejecting the material from the cavity, the filling and ejecting means being operable successively during movement of the movable mold member, container conveying means traveling beneath said movable mold member for conveying containers into a position beneath said mold member to receive the ejected, molded dough material, means for directing a gas stream between said conveyor means and said mold member surface to assist in moving the dough material from the cavity into a container beneath said mold member on said container-conveying means, and control means for synchronizing the movement of containers on the conveyor means with the movement of the mold member so that the ejected molded material will be deposited accurately into a container, said control means comprises container-arresting means and means for releasing the container-arresting means in timed relation with the movement of said movable member so that a container is adapted to pass under the mold member in alignment with a molding cavity.
Claim 3
Dependent Claim
20 words
Apparatus as set forth in claim 1 wherein the means for directing a gas stream comprises an adjustable fishtail-shaped nozzle.
Claim 4
Dependent Claim
48 words
Apparatus as set forth in claim 1 wherein the arresting means comprises pivoted container-arresting and centralizing fingers, and cam means responsive to movement of the mold member for operating the fingers to release a container for travel under the mold member in timed relation with a molding cavity.
Claim 5
Dependent Claim
146 words
Apparatus for molding dough material comprising: a movable mold member having at least one molding cavity in its surface; means for filling the cavity with material to be molded; means for ejecting the material from the cavity, the filling and ejecting means being operable successively during movement of said mold member; container-conveying means mounted below said mold member for conveying containers into position beneath said mold member to receive the ejected molded dough material; and control means for synchronizing the movement of containers on the conveying means with the movement of the mold member so that the ejected molded material will be deposited accurately into a container; said control means comprising container-arresting means and means for releasing the container arresting mEans in timed relation with the movement of the mold member so that each container passes under the mold member in alignment with a molding cavity.
Claim 6
Dependent Claim
146 words
Apparatus for molding dough material comprising: a movable mold member having at least one molding cavity in its surface; means for filling the cavity with material to be molded; means for ejecting the material from the cavity, the filling and ejecting means being operable successively during movement of said mold member; container-conveying means mounted below said mold member for conveying containers into position beneath said mold member to receive the ejected molded dough material; and control means for synchronizing the movement of containers on the conveying means with the movement of the mold member so that the ejected molded material will be deposited accurately into a container; said control means comprising container-arresting means and means for releasing the container arresting mEans in timed relation with the movement of the mold member so that each container passes under the mold member in alignment with a molding cavity.
Claim 7
Dependent Claim
46 words
Apparatus as set forth in claim 4 wherein the arresting means comprises pivoted container arresting and centralizing fingers, and cam means on the drum movable member for operating the fingers to release a container for travel beneath the drum in timed relation with a molding cavity.
