ABSTRACT:
In a preferred embodiment, an elongated base element has as a part thereof, a hinge mechanism mounting a lever for pivotal movement of the lever by a handle whenever movement of the base element causes the handle to strike a cam mounted in the path of movement of the handle attached to the mounted lever, and there being spaced-apart screw-receiving holes in the elongated base element at spaced dimensions such that the screw-receiving holes are alignable with screw-mounting holes in a traveling base and in the selvage pin-mounts and strip carrying the pins, whereby the traveling base is with ease and economically mountable between the strip carrying the pins and the elongated base element, with the lever including a plurality of portions extending across a width of the strip carrying the pins, and with the handle extending downwardly beneath the elongated base element, the lever extending above the elongated base element and above the pin-carrying strip, adapted such that the plurality of portions lying beneath a pinned selvage strip is adapted to lift the selvage strip from a mounted state on the pins to a free state above the pins whenever pressure on the handle causes the lever to pivot the plurality of portions upwardly.
