Segmented roll

A segmented roll comprising:

• a first roll segment having an outer cylindrical shell part having first axial length;
• a first support shaft having a first part and a second part,
• wherein the combined axial length of the first support shaft first part and the first support shaft second part is substantially the same as the first axial length, and wherein the disposition of the first part is alterable with respect to the second part to alter the axial length of the first support shaft;
• bearings positioned on the first support shaft, wherein the first roll segment is mounted by the bearings to the first support shaft;
• an intermediate support member extending from the first support shaft first part, and having an axial end surface;
• and
• an intermediate connection member extending from the first support shaft second part and having an axial end surface, wherein the intermediate connection member end surface is disengageably coupled to the intermediate support member end face of a second like roll segment to permit the first and second roll segments to be disengaged from one another.

A segmented roll comprising

• a first roll segment having an outer cylindrical shell part;
• a first support shaft having a first part and a second part, wherein the disposition of the first part is alterable with respect to the second part to alter the axial length of the first support shaft,
• bearings positioned on the first support shaft, wherein the first roll segment is mounted by the bearings to the first support shaft;
• an intermediate support member extending from the first support shaft first part, and having an axial end surface;
• and
• an intermediate connection member extending from the first support shaft second part and having an axial end surface, wherein the intermediate connection member end surface is disengageably coupled to the intermediate support member end face of a second like roll segment to permit the first and second roll segments to be disengaged from one another, wherein the intermediate connection member has a projection, and the intermediate support member has portions defining a mating recess which faces a projection on a like second roll segment.

A segmented roll comprising

• a first roll segment having an outer cylindrical shell part;
• a first support shaft having a first part and a second part, wherein the disposition of the first part is alterable with respect to the second part to alter the axial length of the first support shaft,
• bearings positioned on the first support shaft, wherein the first roll segment is mounted by the bearings to the first support shaft;
• an intermediate support member extending from the first support shaft first part, and having an axial end surface;
• and
• an intermediate connection member extending from the first support shaft second part and having an axial end surface, wherein the intermediate connection member end surface is disengageably coupled to the intermediate support member end face of a second like roll segment to permit the first and second roll segments to be disengaged from one another, wherein a locking element extends between the first support shaft first part and second part to solidly lock the first part to the second part, the locking element being releasable to permit axial movement of the first part with respect to the second part a distance allowing the intermediate connection member on the first roll segment to be withdrawn from the intermediate support member on the second roll segment.

A segmented roll comprising:

• a first roll segment having an outer cylindrical shell part;
• a first support shaft having a first part and a second part, wherein the disposition of the first alterable with respect to the second part to alter the axial length of the first support shaft,
• bearings positioned on the first support shaft, wherein the first roll segment is mounted by the bearings to the first support shaft;
• an intermediate support member extending from the first support shaft first part, and having an axial end surface;
• and
• an intermediate connection member extending from the first support shaft second part and having an axial end surface, wherein the intermediate connection member end surface is disengageably coupled to the intermediate support member end face of a second like roll segment to permit the first and second roll segments to be disengaged from one another, wherein the first roll segment further comprises:
• an outer shell;
• a disc portion extending radially inwardly from the outer shell;
• an inner shell connected to the disc portion, and thus to the outer shell, the inner shell having a tubular flange portion extending to each side of the disc portion;
• and
• wherein both parts of the first support shaft are provided with an annular recess opening toward an interior of the roll segment, said annular recesses being adapted to accommodate the tubular flange parts of the inner shell, wherein each roll segment is rotatably mounted on the first support shaft by two bearings having inner races which are fixed to the rotating inner shell of the first roll segment and outer races are fixed to inner surfaces of outer walls of the annular recesses.

A segmented roll comprising

• a first roll segment having an outer cylindrical shell part;
• a first support shaft having a first part and a second part, wherein the disposition of the first part is alterable with respect to the second part to alter the axial length of the first support shaft,
• bearings positioned on the first support shaft, wherein the first roll segment is mounted by the bearings to the first support shaft;
• an intermediate support member extending from the first support shaft first part, and having an axial end surface;
• and
• an intermediate connection member extending from the first support shaft second part and having an axial end surface, wherein the intermediate connection member end surface is disengageably coupled to the intermediate support member end face of a second like roll segment to permit the first and second roll segments to be engaged from one another, wherein the first support shaft of the first roll segment is connected at least by one end to a roll segment mounting frame by support means allowing the adjustment of the position and/or distance of support points of the first roll segment in regard to the mounting frame.

A segmented roll comprising:

• a first roll segment having an outer cylindrical shell part;
• a first support shaft having a first part and a second part, wherein the first part engages with the second part within the first roll segment outer cylindrical shell part, and wherein the disposition of the first part is alterable with respect to the second part to alter the axial length of the first support shaft;
• bearings positioned on the first support shaft, wherein the first roll segment is mounted by the beings to the first support shaft;
• an intermediate support member extending from the first support shaft first part, and having an axial end surface;
• and
• an intermediate connection member extending from the first support shaft second part and having an axial end surface, wherein the intermediate connection member end surface is disengageably coupled to the intermediate support member end face of a second like roll segment to permit the first and second roll segments to be disengaged from one another.
