Abstract: An apparatus for preparing elongated products having a cylindrical shell enclosing a core material. The apparatus comprises a plurality of cylindrical moulds each associated with a core member which is laterally supported in a frame moving in unison with the moulds through the apparatus. Fluent raw materials are supplied to each mould and caused to solidify to form the finished products. The core members are axially displaceable in the supporting frame, and each core member is lowered into the associated mould before any of the raw materials is supplied. It is withdrawn from the mould when the material of the shell has been sufficiently solidified to permit the withdrawal. Before being withdrawn the core member may be rotated through a fraction of a revolution to facilitate its release from the product shell. When in their raised position, the core members are held against axial displacement and rotation by detent means on the frame.

Abstract: An apparatus for preparing edible products having a cylindrical shell of coagulated egg-white enclosing a central core. The apparatus has a plurality of cylindrical moulds moving cyclically in a closed path including stations in which raw materials are supplied and stations in which the finished products are withdrawn from the mould. Each mould is provided with a vertically displaceable bottom plug, which is pushed upwards to permit withdrawal of the finished product. It is subsequently pushed to the bottom of the mould by means of a rod carrying a pad for applying a metered amount of a lubricating agent onto the mould surface before a core member is inserted in the mould and the raw materials are supplied. Means are provided for cleaning the mould wall during the upward movement of the bottom plug.
