Abstract
An improved slipform for use in a machine for casting hollow core concrete planks includes at least one angled baffle plate in the core material receiving ports so as to deflect the core material from directly impacting the lower concrete. This lessens the possibility of tears and holes in the lower layer caused by the core material.
