Abstract
Apparatus for rounding the spines of book blocks comprises rounding elements that act on the sides of the book block, the action of these rounding elements being due to a defined rotation and pressure, the rounding elements consisting of rounding segments which are drive-rotated by actuating mechanisms and can be moved vertically to thereby execute rolling movements on the sides of the book block. The vertical movement of said rounding segments are superimposed on their rotation in a manner such as to compensate for the vertical movement of the book block generated as a consequence of the rotation.
Claims23
Apparatus for rounding the spines of book blocks, the rounding apparatus serially receiving book blocks to be shaped from a transport system having book block clamps, said rounding apparatus comprising:
- oppositely disposed rounding elements for engaging and acting on the opposite sides of a book block upon the release of the book block from a transport system clamp, said rounding elements each being provided with two shaped working segments which define book contacting zones on a face of the rounding element, each of said zones having a different radius whereby a book block engaged by said rounding elements may selectively be formed to a pre-selected rounding curve shape commensurate with one of said zone radii;
- means for imparting motion relative to the book block to said rounding elements;
- and
- means for biasing said rounding elements against the sides of the book block during the motion thereof.
Apparatus for rounding the spines of book blocks, the rounding apparatus serially receiving book blocks to be shaped from a transport system having book block clamps, said rounding apparatus comprising:
- a pair of oppositely disposed rounding elements for engaging and acting on the opposite sides of a book block upon the release of the book block from a transport system clamp, said rounding elements each being provided with at least a pair of shaped working segments which define book contacting zones on a face of the rounding element, each of said zones having a different shape whereby a book block engaged by said rounding elements may selectively be formed to a pre-selected rounding curve shape commensurate with one of said zone shapes, said rounding element segments being provided on the same face of each rounding element, two of said rounding elements being provided on each side of the book block;
- means for simultaneously imparting rotation and substantially linear motion relative to the book block to said rounding elements to thereby cause said rounding elements to execute rolling movements along the sides of the book block, the relative motion being superimposed on the rotation, said motion imparting means causing a book contacting zone on each said rounding element on each side of the book block to be brought into functional contact with the sides of the book block in an alternating manner;
- and
- means for biasing said rounding elements against the sides of the book block during the rolling movement thereof.
Apparatus for rounding the spines of book blocks, the rounding apparatus serially receiving book blocks to be shaped from a transport system having book block clamps, said rounding apparatus comprising:
- a pair of oppositely disposed rounding elements for engaging and acting on the opposite sides of a book block upon release of the book block from a transport system clamp, said rounding elements each being provided with at least a pair of shaped working segments which define book contacting zones on a face of the rounding element, each of said zones having a different shape whereby a book block engaged by said rounding elements may selectively be formed to a pre-selected rounding curve shape commensurate with one of said zone shapes, said rounding elements each being comprised of a pair of book block contacting members, the first of said members defining a first of said zone shapes on an outer surface thereof, the second of said members defining the second of said zone shapes on an outer surface thereof, an inner surface of said first member being disposed oppositely to the said outer surface thereof and being complementary in shape to the outer surface of said second member, said first member being removably mounted over said second member when the selected rounding curve shape is commensurate with said first of said zone shapes;
- means for imparting motion relative to the book block to said rounding elements;
- and
- means for biasing said rounding elements against the sides of the book block during the motion thereof.
