Abstract

This invention discloses a horizontal multistage press which comprises a pair of frames disposed upright in face-to-face relationship with each other, at least one upper lateral beam disposed to connect the upper portions of the abovementioned pair of frames, at least one lower lateral beam disposed to connect the lower portions of the pair of frames, rails disposed on at least either of such pair of upper and lower lateral beams and extending along the length thereof, a multiplicity of hot plates disposed parallel to one another between the pair of frames and supported by the rails for reciprocal movement along the length of such rails, a multiplicity of unprocessed sheets being heat-pressed between the hot plates, at least one urging means disposed on at least one of the frames for urging the multiplicity of hot plates toward and away from one another, and travel members for loading and unloading the unprocessed and processed sheets in and from the gaps between the hot plates, such travel members including at least one engagement members for engaging the lower ends of the unprocessed and processed sheets.

Dependent claims

A horizontal multistage press comprising:

(a) a pair of frames disposed upright in face-to-face relationship with each other;
(b) at least one upper lateral beam for coupling the upper portions of said pair of frames;
(c) at least one lower lateral beam for coupling the lower portions of said pair of frames;
(d) rail means disposed on at least one of said upper end lower lateral beams and extending along the length thereof;
(e) a multiplicity of hot plates disposed parallel to one another between said pair of frames and supported by said rail means for reciprocal movement along the length of said rail means, a multiplicity of unprocessed sheets being heat-pressed between said hot plates to produce processed sheets;
(f) at least one urging means disposed on at least one of said frames for urging said multiplicity of hot plates toward and away from one another;
(g) travel means for loading said unprocessed sheets in and unloading processed sheets from the gaps between said hot plates, said travel means including a carrying conveyor having a plurality of first rolls disposed under said hot plates, a loading conveyor having a plurality of second rolls disposed on the side on which said unprocessed sheets are loaded, and an unloading conveyor having a plurality of third rolls disposed on the side on which said processed sheets are unloaded, said first, second and third rolls having engagement means on at least one roll thereof, respectively, for engaging the lower ends of said unprocessed and processed sheets while said sheets are being maintained in an upright state so as to force said sheets between said hot plates to travel even where said sheets include defects such as unevenness, curvature and the like thereon;
and stopper means adapted to adjustably engage the leading ends of said unprocessed sheets at different ones of a plurality of positions along the direction of travel of said unprocessed sheets to stop said unprocessed sheets between said hot plates at a desired one of a plurality of predefined positions corresponding to the length of said unprocessed sheets, thereby allowing sheets of different lengths to be centrally accommodated between said hot plates.

A horizontal multistage press comprising:

(a) a pair of frames disposed upright in face-to-face relationship with each other;
b) a multiplicity of hot plates disposed parallel to one another for reciprocal movement between said pair of frames, said hot plates heat-pressing a multiplicity of unprocessed sheets therebetween;
(c) urging means disposed on at least one of said frames for urging said multiplicity of hot plates toward and away from one another;
(d) means for advancing a multiplicity of sheets between said hot plates in a direction parallel to said hot plates;
and
(e) stopper means adapted to adjustably engage the leading ends of said unprocessed sheets at different ones of a plurality of positions along the direction of travel of said unprocessed sheets to stop said unprocessed sheets between said hot plates at a desired one of a plurality of predefined positions corresponding to the length of said unprocessed sheets, thereby allowing sheets of different lengths to be centrally accommodated between said hot plates.
