A ribbon take-up hub for a printer is disclosed. The ribbon take-up hub comprises a centre hub configured to be coupled to a rotatable component of the printer. The centre hub comprising a button. Further, one or more arc shaped blocks are positioned in proximity to the centre hub, and a plurality of tension holders are attached to the centre hub. Further, upon pressing of the button, the plurality of tension holders retracts inside the centre hub to facilitate placement and winding of a ribbon between the plurality of tension holders and the one or more arc shaped blocks. Further, upon releasing the button, the plurality of tension holders extends from the centre hub to clamp the winded ribbon between the plurality of tension holders and the one or more arc shaped blocks.

A system for deploying a coil of spoolable pipe from a vessel includes a first tower configured to move longitudinally and transversely along a first track coupled to the vessel, a second tower configured to move longitudinally along a second track coupled to the vessel, and a coil drum assembly coupled to the first tower. The first tower is configured to insert the coil drum assembly transversely into an interior channel of the coil when the coil drum assembly is in a retracted position, the coil drum assembly is configured to support the coil when the coil drum assembly is in an extended position and rotate during deployment of the spoolable pipe, and the first tower and the second tower are configured to move the coil drum assembly vertically.

A roller for supporting a material according to an embodiment of the present invention includes: a rotation shaft; a pipe having a space in which the rotation shaft is inserted; a deforming part that is connected to the rotation shaft and the pipe to deform the pipe; and a support part that is installed at the pipe to support the material. The deforming part includes: a thread portion provided on the rotation shaft; a nut part screwed to the thread portion; an inclined part that is disposed at an inner surface of the pipe and that is pressed by the nut part according to rotation of the rotation shaft; and a driving source that is connected to the rotation shaft to rotate the rotation shaft.
