The frame member includes a base, a first sidewall and a second sidewall. The first sidewall and the second sidewall extend upwardly from the base. The at least one shaft member disposed between the first sidewall and the second sidewall such that a first end portion and a second end portion extend outwardly away from the first sidewall and the second sidewall, respectively. The at least one shaft member is rotated for wrapping the sheet material around the first end portion, and for unwrapping the sheet material from the first end portion over the objects. The locking member is disposed on the second end portion of each of the at least one shaft member for locking and unlocking rotation of the each of the at least one shaft member. ## Claims ### Claim 1 A device for applying a sheet material over objects, the device comprising: a frame member comprising a base, a first sidewall and a second sidewall, wherein each of the first sidewall and the second sidewall extends upwardly from the base in a spaced apart relation with each other; at least one shaft member comprising a first end portion and a second end portion opposite to the first end portion, the at least one shaft member rotatably disposed between the first sidewall and the second sidewall such that the first end portion and the second end portion extend outwardly away from the first sidewall and the second sidewall, respectively, wherein the at least one shaft member is capable of being rotated for wrapping the sheet material around and onto the first end portion, and, wherein the at least one shaft member is capable of being rotated for unwrapping the sheet material from the first end portion over the objects; and a locking member disposed on the second end portion of each of the at least one shaft member, the locking member is capable of locking and unlocking rotation of the each of the at least one shaft member, wherein the locking member comprises a band member adapted to encircle the second end portion of the each of the at least one shaft member, and a lever assembly connected to the band member, the lever assembly capable of being locked at various positions for enabling the band member for locking a rotation of the shaft members during wrapping and unwrapping of the sheet material over the objects. ### Claim 2 (depends on 1) The device of claim 1, wherein the frame member further comprises at least one channel member disposed at the base thereof, the at least one channel member receives a portion of a lifting device for moving the device for wrapping and unwrapping the sheet material from the first end portion of the at least one shaft member over the objects. ### Claim 3 (depends on 1) The device of claim 1, wherein the frame member further comprises at least one supporting member arranged between the first sidewall, the second sidewall and the base for stabilizing the frame member. ### Claim 4 (depends on 1) The device of claim 1, wherein the at least one shaft member further comprises at least one attaching element attached to the first end portion thereof, the at least one attaching element capable of attaching the sheet material to the at least one shaft member for wrapping the sheet material around and onto the first end portion. ### Claim 5 (depends on 1) The device of claim 1 further comprising an auxiliary shaft member rotatably disposed between the first sidewall and the second sidewall such that a first end portion and a second end portion thereof extend outwardly away from the first sidewall and the second sidewall, further, the first end portion having a free end thereof away from the first sidewall, wherein the auxiliary shaft member is capable of being rotated for wrapping an auxiliary sheet material around and onto the first end portion thereof, and wherein the auxiliary shaft member is capable of being rotated for unwrapping the auxiliary sheet material from the first end portion for applying over the objects for covering the objects. ### Claim 6 (depends on 5) The device of claim 5, wherein the auxiliary shaft member further comprises a stopper at the free end of the first end portion thereof for preventing the auxiliary sheet material from slipping out of the auxiliary shaft member. ### Claim 7 A device for applying a sheet material over objects, the device comprising: a frame member comprising a base, a first sidewall and a second sidewall, wherein each of the first sidewall and the second sidewall extends upwardly from the base in a spaced apart relation with each other; at least one shaft member comprising a first end portion and a second end portion opposite to the first end portion, the at least one shaft member rotatably disposed between the first sidewall and the second sidewall such that the first end portion and the second end portion extend outwardly away from the first sidewall and the second sidewall, respectively, wherein the at least one shaft member is capable of being rotated for wrapping the sheet material around and onto the first end portion, and, wherein the at least one shaft member is capable of being rotated for unwrapping the sheet material from the first end portion over the objects; and a locking member disposed on the second end portion of each of the at least one shaft member, the locking member comprising a band member adapted to encircle the second end portion of the each of the at least one shaft member, and, the locking member further comprising a lever assembly connected to the band member, the lever assembly capable of being locked at various positions for enabling the band member for locking a rotation of the shaft members during wrapping and unwrapping of the sheet material over the objects.
