Abstract
A slicing apparatus for dividing a compression-molded article of laminae is provided with a dividing knife that reciprocates within a horizontal plane, and the dividing knife has a cutting edge in the shape of a V directed toward the compression-molded article, and cuts into the compression-molded article while holding the article from both sides.
Claims17
An apparatus for slicing a compression-molded article of sheet-like materials, comprising:
- ascending/descending means including a lifter for receiving the compression-molded article of the sheet-like materials and used to raise and lower said compression-molded article together with the lifter;
- dividing means for dividing the compression-molded article on said lifter into a first piece with a given thickness and a second piece, said dividing means including a dividing knife capable of moving toward said lifter in a first direction along a straight line and within a horizontal plane, thereby cutting the compression-molded article on said lifter, said dividing knife including an effective cutting edge region recessed with respect to said compression-molded article obtained by cutting;
- and
- discharge means for discharging said first piece from the upper surface of said dividing knife in a second direction substantially perpendicular to said first direction to a position beside said dividing knife.
A dividing knife capable of horizontally moving toward a compression-molded article of sheet-like materials, thereby dividing said compression-molded article into pieces with a given thickness, the dividing knife including an effective cutting edge region having a central portion recessed with respect to outermost side edge portions of said effective cutting edge region such that said central portion is located further from said compression-molded article than said outermost side edge portions, wherein said effective cutting edge region of said dividing knife is V-shaped with respect to said compression-molded article.
A dividing knife capable of horizontally moving toward a compression-molded article of sheet-like materials, thereby dividing said compression-molded article into pieces with a given thickness, the dividing knife including an effective cutting edge region having a central portion recessed with respect to outermost side edge portions of said effective cutting edge region such that said central portion is located further from said compression-molded article than said outermost side edge portions, wherein said effective cutting edge region of said dividing knife is W-shaped with respect to said compression-molded article and has a chevron-shaped cutting edge portion in the center recessed behind opposite ends of cutting edge portions on either side.
An apparatus for slicing a compression-molded article of sheet-like materials, comprising:
- a lifter for receiving the compression-molded article of the sheet-like materials and for raising and lowering said compression-molded article;
- a dividing knife for dividing the compression-molded article on said lifter into a first piece with a substantially uniform thickness and a second piece, said dividing knife movable toward said lifter in a first direction along a straight line from a retracted position where said dividing knife has not penetrated said compression-molded article to an extended position where said dividing knife has passed through said compression-molded article, thereby cutting the compression-molded article on said lifter, said dividing knife further including an upper surface for holding the first piece of said compression-molded article obtained by cutting;
- and
- a discharge member for discharging said first piece from the upper surface of said dividing knife in a. second direction substantially perpendicular to said first direction to a position beside said dividing knife.
