Abstract: This invention relates to a method and a device for automatically binding book blocks by machine. In a working cycle, the book blocks are conveyed on a conveyor device in an upright manner through the individual processing stations. In a fanning gluing binding station (2), adhesive is applied from underneath against the fanned book block spine. In a spine-taping station (3) the spine-taping material is directly pulled off a roll and is automatically cut to the predetermined measure by machine. The headband is likewise pulled off a roll, cut to the required dimensions, advanced to the book block by means of a slide and is ironed onto the book spine. Afterwards, the end paper of the book block provided with the headband is opened in order to attach the book cover to the book block, is pulled from the book block by suction, and is clamped in a lower station press. With the end paper opened, the book block is then placed in a covering station (5), and the book block is fixed to the book cover.

Abstract: This invention relates to a boring tool having a cutting insert. The insert has a chip breaker with a base that extends from the secondary cutting edge to the primary cutting edge. The primary cutting edge, which is also referred to below as the major cutting edge, thereby runs diagonally with respect to the insert surface or top face of the indexable insert toward the chip breaker base of the chip breaker. The secondary cutting edge, which is also referred to as the minor cutting edge below and is advantageously straight, descends toward the major cutting edge, as a result of which a wiper geometry is realized on the minor cutting edge. Therefore the major cutting edge and the minor cutting edge preferably form a closed triangle with the chip breaker base.

Abstract: An end prep tool with a pneumatically driven tool slide assembly comprises a mandrel mountable to the internal diameter of a tubular work piece. Mounted on the mandrel are a rotational head assembly and a rotatable housing that are longitudinally displaceable along the mandrel. The rotational head assembly carries either one or two tool feed assemblies thereon for orbital movement around the work piece. The tool slide assemblies are driven by a pneumatic motor to provide a true phonographic finish with no tripper marks.

Abstract: A polygonal indexable insert has cutting edges that run rectilinearly or in a curved manner in a plane perpendicular to a locating surface and that fall from cutting corners having acute angles to cutting corners with obtuse angles following one another alternately. The cutting edges have a rake face which first of all falls and then rises with a back region. The back region together with a center part of the indexable insert forms an intersection curve. The intersection curve lies at a distance a from the starting point of the associated cutting edge in the region of the cutting corners in each case at their intersection with the angle bisector. It is at a distance b from the end point of the associated cutting edge in the region of the cutting corners in each case at their intersection with the angle bisector. The distance b is greater than the distance a.

Abstract: 12. A rotationally drivable milling cutter has a cylindrical carrier body (10), which is equipped on its circumference with a plurality of cutting bodies (12) comprising a cutting material that is harder than hard metal. The cutting bodies (12) are embodied in platelike form and are each embodied and disposed such that the leading region of the radially outer circumferential edge forms the cutting edge, the adjacent side face (15) forms the first face with a negative rake angle, and the top face (17) diametrically opposite the bottom face forms the flank. To that end, the cutting bodies (12) are each secured with their bottom face on the end face of blind bores (30), in the circumferential face thereof, that are oriented with the angle to the shortest connecting line between the center point of the end face and the center longitudinal axis of the carrier body (10) such that the side face (15) adjacent to the cutting edge forms the predetermined rake angle.
