ABSTRACT
The invention concerns a method and apparatus for severing
the jowl muscles of a half pig's head, in order to
facilitate subsequent boning of the half head to provide
bone and pig's head meat as the end product.
For this purpose, in one embodiment of the invention,
the half pig's head (19) is placed on a moving conveyor
(11) comprising a series of stainless steel plates (12),
the half head being held securely in a predetermined
position by a locating and supporting means (13 to 18)
welded to the plate (12). The half head so held is
presented by the conveyor to a fixed wedge member (20)
pointing in the opposite direction to that of the
conveyor movement, the wedge member acting to force
the jaws of the half head progressively further apart
to sever the jowl muscles.
Preferably, the outer skin or rind of the half head is
removed before the latter is placed on the conveyor. This
is achieved manually by an operative using a knife, the
half head during this operation being placed on a table
(26) and held in position by a wire loop (28) which
holds the snout of the half head tightly against a post
(27).
