Abstract: A production method for a glass roll includes a start preparation step (S1) of feeding-out a first lead film (LF1) coupled to a starting end portion (GFa) of a first glass film (GF1) from an unwinding device (3) and allowing a winding device (8) to wind the first lead film (LF1 after passing of the first lead film (LF1) through a thermal film-forming device (4),). The start preparation step (S1) includes a temperature increasing step of causing the thermal film-forming device (4) to be increased in temperature to a film-forming temperature. The first glass film (GF1) reaches the thermal film-forming device (4) before the thermal film-forming device (4) is increased in temperature to the film-forming temperature.

Abstract: In a manufacturing method of a glass roll, a transport device transports a glass film coupled to lead films via coupling portions. The transport device separates the lead films and/or the coupling portions from a heating roller when the lead films and/or the coupling portions pass by the heating roller.

Abstract: Efficient plunge cutting work in which the tool body moves forward and backward in the axial direction to cut the wall face of a workpiece at high feed-speed, is possible even in the cutting process with backward motions. The tool body 1 has a cylindrical shape with an axis O as its center axis, and provides the insert pocket 3 in the outer periphery close to the tip. The cutting insert 10 is detachably attached in the insert pocket 3. Then, by rotating the tool body 1 and by feeding it along the axis O, the cutting insert 10 cuts the wall face of a workpiece. Furthermore, the insert pocket includes a bottom face which faces the tool rotational direction and, wall faces 3B, 3C and 3D which extend from the bottom face toward the tool rotational direction.

Abstract: To enable a rotary cutter to correspond to an automatic tool exchange apparatus by adjusting, in a peripheral direction, the position of a positioning member in response to an outlet of a chip container and a key and a key seat for receiving the key of a rotary cutter and a machine tool. A chip container having an outlet is mounted on the peripheral area of a cutter body with a bearing therebetween. An arbor of the cutter body is connected to a machine tool such that a key fits into a key seat, and at the same time a positioning pin of the chip container is inserted into a fitting recess of a spindle head. A movable block ring having the positioning pin is mounted on the chip container after adjusting in a peripheral direction, and is fastened with a bolt. Even when a key of the machine tool and a fitting recess differ in a peripheral direction, they can be adjusted. The relative position in a peripheral direction between the outlet of the chip container and the positioning pin can be adjusted.

Abstract: First and second tips 4A and 4B are disposed on the outer periphery of the forward end of an end mill body 1 in a manner such that the tips 4A and 4B are displaced from each other about the periphery of the end mill body 1. The rotation loci of edges of the first and second tips 4A and 4B around the axis O of the end mill body 1 are mutually overlapped. The edge of the first tip 4A protrudes slightly farther toward the forward end of the end mill than the edge of the second tip 4B. Further, third tips 4C are disposed adjacent to the base end of the second tip 4B in such a manner that no gap is formed between the rotation locus of the edge of the third tip 4C located most adjacent to the forward end of the end mill body and the rotation locus of the rear end of the second tip 4B. As a consequence, the second tip 4B and the third tips 4C can be spirally disposed in the rearward rotating direction of the end mill as they extend toward the base end of the end mill.
