Title: Cutting of adheive tape roll
Inventor: SUMI KOICHI
IPC: C09J7/02
Filed: 1992-11-24
Abstract: PURPOSE:To provide a highly safe cutting method of an adhesive tape roll, by which no damage is caused by friction by cutting the adhesive tape roll, for which an adhesive tape layer is formed on the outer periphery of a paper core layer, at different cutting angles of a cutting blade between the paper core layer and the adhesive tape layer. CONSTITUTION:A cutting blade 4 is adjusted at a cutting angle of theta1 in relation to a roll surface 5 when an adhesive tape roll 3 is to be cut, and an adhesive tape layer 1 is thus cut. As the cutting blade 4 is tilted by 5 deg. relative to a cutting surface 6, a relief of the cutting blade 4 at the time of cutting the adhesive tape layer 1 is prevented, and the adhesive tape layer 1 is cut perpendicular to the roll surface 5. The cutting angle of the cutting blade 4 is changed to a cutting angle of theta2 which is suitable to cutting of a paper core layer 2, at the same time as the cutting of the adhesive tape layer 1. Namely, the paper core layer 2 is cut perpendicular to the roll surface 5, while the cutting angles theta1, theta2 of the cutting blades 4 are changed in cases of the adhesive tape layer 1 and the paper core layer 2. The adhesive tape layer 1 and the paper core layer 2 can thus be cut perpendicular to the roll surface. Safe cutting is carried out without deviation.

Title: Apparatus for manufacturing paper block and paper block product manufactured by the apparatus
Inventor: BUCK HERMANN
IPC: B42B9/00
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To increase a combining strength for combining together a block coating layer and each block layer. SOLUTION: With the use of a block manufacturing apparatus 20, a block coating layer 3 is at first pulled so as to be separated from a block 1 at a separating portion 37. Then, the block coating layer 3 is separated from the central portion of the block and such a separation is thereafter extended to surrounding edge portions. Subsequently, a sort of adhesive layer is separated from an adhesive supplying means 60, and bonded to the edge portions of the block and the internal surfaces of a block coating layer 3. The block coating layer 3 is then guided together with the block main body to an adhering section 42. In this way, the block coating layer 3 is directly and planarly bonded to an external surface of a block, thereby preventing a racking or undesired separation which may be possibly caused due to an operation mistake.

Title: Molding method for shadow mask
Inventor: ITO MASAHIRO
IPC: H01J9/14
Filed: 1989-12-04
Abstract: PURPOSE:To obtain a shadow mask with no deformation and with high precision by stretch-pressing the curved surface of a shadow mask while moving a punch to a position slightly lower than the curved surface of a punch pressure pad. CONSTITUTION:A pressure pad 5 is lowered, a shadow mask raw material 7 is pinched by a die 2 and the pressure pad 5, and the shadow mask raw material 7 is restricted by a bead groove 2a and a bead 5a provided on the die 2 and the pressure pad 5. The curved surface of the shadow mask is stretch- pressed by the punch 4 and a knockout 1 while moving the punch 4 down to a position slightly lower than the curved surface of the pressure pad 5, and the punch 4 is further lowered to form the skirt section of the shadow mask. The shadow mask raw material 7 is stretched in the outer periphery direction by the step difference between the curved surface of the punch 4 and the curved surface of the pressure pad 5 at the time of stretch pressing, the excessive amount is absorbed, thus the deformation of the curved surface of the shadow mask is prevented, and the shadow mask with high precision is obtained.

The mirror 50, therefore, forms the mirror image of the mirror 30 in the position shown at the point Q. The display contents of the meter 20 are imaged by the mirrors 30, 50 in such a case and, therefore, the images are formed in the position forward of the imaging position of the mirror 30, i.e., the position forward by as much as the sum of the object point side distance of the mirror 50 and the 1st image point side distance. The imaging position of the display contents is thus further away than the single half mirror.
