Claims
- 1. 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.
- 2. The apparatus according to claim 1, wherein said dividing means further comprises upper presser means for pressing an upper surface of said compression-molded article when said compression-molded article is cut.
- 3. The apparatus according to claim 2, wherein said upper presser means is located above a portion of said upper surface which is situated on a side through which said dividing knife exits said compression-molded article.
- 4. The apparatus according to claim 1, wherein said dividing means further includes side stopper means for pressing a side face of said compression-molded article which is situated on a side through which said dividing knife exits said compression-molded article.
- 5. 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.
- 6. The dividing knife according to claim 5, wherein said effective cutting edge region has an angle of 60 to 120°.
- 7. 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.
- 8. 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.
- 9. The apparatus according to claim 8, further comprising an upper presser device for pressing an upper surface of said compression-molded article when said compression-molded article is cut.
- 10. The apparatus according to claim 9, wherein said upper presser device is located above a portion of said upper surface which is situated on a side through which said dividing knife exits said compression-molded article.
- 11. The apparatus according to claim 8, further comprising at least one side stopper for pressing a side face of said compression-molded article which is situated on a side through which said dividing knife exits said compression-molded article.
- 12. The apparatus according to claim 8, wherein said dividing knife includes a cutting edge with a central portion recessed with respect to outermost side edge portions thereof such that said central portion is located further from said compression-molded article than said outermost side edge portions when said dividing knife is in said retracted position.
- 13. The apparatus according to claim 12, wherein said cutting edge of said dividing knife is V-shaped with respect to said compression-molded article.
- 14. The apparatus according to claim 13, wherein said cutting edge has an angle of 60° to 120°.
- 15. The apparatus according to claim 12, wherein said cutting edge 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.
- 16. The apparatus according to claim 12, wherein said cutting edge of said dividing knife has the shape of a U spread toward said compression-molded article.
- 17. The apparatus according to claim 12, wherein said cutting edge of said dividing knife has the shape of a circular arc with respect to said compression-molded article.
