Abstract:
A flour milling roll machine comprising:a machine frame; at least a pair of rolls within the machine frame and which are driven in a different circumference speed between said paired rolls; a roll gap adjusting means for adjusting a roll gap between said paired rolls; a stock feeding means for feeding raw material stock in a thin layer state to the gap between said paired rolls; a front door for covering an opening in said machine frame located at a diagonally upper side of said paired rolls, said front door having a hinge at its upper edge portion connected to an upper portion of said opening so that it is swung outwardly and upwardly about said hinge and finally is kept at a self-supporting position; a roll cover divided into a main roll cover for covering over an upper portion of said paired rolls, and a feed roll cover for covering said stock feeding means; a first fulcrum axis arranged between said main roll cover and one end of said feed roll cover, said main roll cover being foldable on said feed roll cover about said first fulcrum axis; and a second fulcrum axis arranged between the other end of said feed roll cover and an internal predetermined portion of said machine frame, said feed roll cover being swung outwardly and upwardly about said second fulcrum axis with said main roll cover being kept as the folded state and finally being kept as the self-supporting position, wherein, where said front door is opened in the self-supporting position, said roll cover is exposed; where said main roll cover is folded about said first fulcrum axis over said feed roll cover, a part of upper portions of said paired rolls is exposed and, further, where said feed roll cover is swung about said second fulcrum axis and is finally kept at the self-supporting position, the entire upper portions of said paired rolls and said stock feeding means are exposed so that remaining stock accumulated thereon can be removed with ease.
