초록 ▼

A hot plate for a double facer used in the manufacture of corrugated paperboard includes a substantially all copper construction which enhances thermal conductivity and heat transfer efficiency. Steam for heating the plates is provided through an array of copper tubes extending between manifolds on opposite sides of the hot plate, all in a manner which obviates the need for heavy pressure vessel construction. The hot plate is allowed to float on its supporting frame in a manner which accommodates lateral thermal expansion, and the lateral ends are tied vertically to the supporting frame to prevent thermal bowing characteristic of prior art systems.

대표청구항 ▼

A hot plate for supporting and heating a traveling web of corrugated paperboard in a double facer comprising: a web supporting top plate made of a non-ferrous metal having a high thermal conductivity; a series of spaced generally parallel open-ended non-ferrous metal tubes extending transverse to the direction of web travel, positioned in a planar array beneath and in operative heat conducting contact with the underside of said top plate; a pair of manifolds attached to the top plate, each manifold connecting the open ends of the tubes along one lateral edge of the top plate; a source of a heated fluid operatively connected to said manifolds; means for transferring the heated fluid through said tubes between the manifolds; a lower steel supporting frame including a bottom plate adapted to underlie said top plate in parallel vertical spaced relation thereto; anchoring means rigidly interconnecting the top plate and said bottom plate midway between said manifolds; and, vertical holddown means connecting the manifolds to the lateral outer edges of the supporting frame for preventing upward bowing of the top plate caused by thermally induced vertical. movement of the lateral edges of the top plate and for allowing horizontal lateral movement thereof caused by thermal expansion of the top plate in opposite directions from said anchoring means.
