Abstract

In tape handling systems where a plurality of guide spindles is employed to guide the tape through a circuitous path, misalignment of the spindles, i.e., spindle surface not conforming exactly with the plane of the desired tape path, causes uneven distribution of wrap tension. This results in tape stretching, tearing or bunching.

Self Aligning Spindle

In tape handling systems where a plurality of guide spindles is employed to guide the tape through a circuitous path, misalignment of the spindles, i.e., spindle surface not conforming exactly with the plane of the desired tape path, causes uneven distribution of wrap tension. This results in tape stretching, tearing or bunching.

This spindle provides a pivotable tape guiding sleeve 5 which automatically aligns itself, as the tape slides over it, to evenly distribute the wrap tension across the tape surface. A bushing or washer 3 is positioned approximately in the center of spindle post 1 against shoulder 2.

Spacer shim 4, secured at one end by press fit washer 6, maintains 3 in position. Thus, when 1 is out of square with the tape path, the tape tension pivots 5 on 3 to bring the surface of 5 into correct alignment with the tape.
