A dolly for moving a bendable roll of material such as a carpet and bending it to fit into a confined space, such as an elevator, includes a primary section capable of supporting a first portion of the roll and having ground-engaging wheels, and a: secondary section pivotally connected to the primary section and capable of supporting a second portion of the roll. The secondary section is pivotally movable relative to the primary section from a lowered position in which the secondary section provides either as a longitudinal extension of the first portion, or in a raised position with the roll bent. A stop member limits lengthwise movement of the roll along the primary section. A carpet roll resting on the dolly may be bent at a central area by lifting the secondary section to the raised position and applying downwards force on the central area of the roll.

We claim: 1. A dolly for moving a bendable roll of material, including a roll of 12 foot length, and for facilitating the bending of the roll, including: a) a primary section capable of supporting a first portion of said roll at several locations along its length which first portion is at least 7 feet in length, said primary section having first and second ends, and having ground-engaging wheels adjacent each of said ends; b) a stop member at the first end of said primary section and adapted to limit lengthwise movement of the roll along said primary section, c) a secondary section pivotally connected to the second end of said primary section and having side members connected by cross members capable of supporting a second portion of said roll which is at least one-third the length of a 12 foot roll, said secondary section being pivotally movable relative to the primary section between: 1) a lowered position, in which the secondary section provides a longitudinal extension of the primary section, 2) a raised position, such that a bendable roll resting on both sections of the dolly may be bent at a central area by lifting the secondary section from the lowered to the raised position while applying downwards force to said central area, with the secondary section providing leverage for bending the roll, and 3) a stored position wherein the secondary section is folded flat on top of the primary section to reduce the overall length of the dolly for storage; and d) a tension element for connecting the primary and secondary sections to hold the secondary section in said raised condition. 2. A dolly according to claim 1, wherein the tension element for holding the secondary section in the raised position is a flexible element capable of connecting spaced parts of the primary and secondary sections. 3. A dolly according to claim 1, wherein said primary section includes side members joined by support means which provide a bed for the roll, the primary section side members being higher than central portions of the bed to assist in holding the roll laterally in place on the dolly. 4. A dolly according to claim 1, wherein said dolly is provided with a removable U-shaped extension member, said extension member being adapted to be positioned selectively in a first position, where said legs fit onto an outer end of said secondary section and said extension member forms an extension of the secondary section to thus provide additional leverage for raising the secondary section while bending said roll, and in a second position in which said legs fit onto brackets connected to said primary section from which said extension member projects upwardly and provides an upwardly extending handle for moving the dolly. 5. A dolly according to claim 1, in which said primary section includes at least two telescoping portions. 6. A process for bending a carpet roll to enable the roll to fit within a confined space, comprising the steps of: a) placing said roll on a dolly having a primary section and a secondary section, said primary section being capable of supporting a first portion of said roll which portion is at least 7 feet in length, said primary section having first and second ends and having ground-engaging wheels adjacent each end, and the secondary section being pivotally connected to the second end of the primary section and being capable of supporting a second portion of said roll, said secondary section being pivotally movable relative to the primary section, b) lifting said secondary section pivotally from a lowered position, in which the secondary section provides a longitudinal extension of the primary section, to a raised position by utilizing leverage provided by said secondary section during lifting and simultaneously applying downwards force to a central portion of the roll to cause the roll to bend, whereby the overall dimensions of the roll are altered to allow it to fit into said confined space. 7. A process according to claim 6, wherein, after the secondary section has been lifted, it is secured in its raised position by a flexible or rigid tension element connecting the sections. 8. A process according to claim 6, wherein the step of lifting the secondary section is achieved by attaching a removable extension member to said secondary section to provide additional leverage.
