Abstract: A molding apparatus for forming comestible shapes includes a mold block having an open ended cavity formed therein, the cavity having an axis of symmetry generally transverse to a plane of its open end, and movable means for closing the open end during molding to retain the comestible within the cavity. A scraper pivotally mounts at just one point on the mold block for rotation about the axis of symmetry within the cavity, and a conduit valve provides a flow of comestible in a plastic state into the mold cavity. Control means controls the flow of comestible into the cavity, the rotation of the scraper, and the opening and closing of the movable means to permit shaping of the comestible within the mold cavity and release of the shaped comestible from the mold cavity by operation of the valve, the movable means, and the scraper. In one embodiment, a conduit houses a displacement valve controlled to provide a negative flow pressure after filling of the mold.

Abstract: A melt spinning apparatus is disclosed which is adapted for dividing a molten polymer into a plurality of streams to form synthetic filaments. The apparatus comprises a spin block assembly having two opposite sides, and two separate heating chambers disposed adjacent respective ones of the sides of the spin block assembly. The two heating chambers are interconnected by threaded members, so that the opposing surfaces of the chambers may be drawn together to clampingly engage the opposite sides of the spin block assembly therebetween. The formation of air gaps between the opposing surfaces, and which might hinder the heat transfer between the heating chamber and spin block, are thereby avoided.
