Abstract: An apparatus for the facile installation of non-cylindrical marker sleeves on wire-like members such as electrical wiring or cable. The apparatus is particularly directed to the handling of non-cylindrical marker sleeves which are tightly and slidably arranged on fingers of a carrier belt. A stripper mechanism employing a series of split tines is slidably positioned on a base capable of fixedly holding the carrier belt and fingers. The split tines are directed along either side of each finger to engage a first end of each non-cylindrical sleeve and to force the sleeve from its supporting finger. A die is fixed to the base to receive the sleeves as they are stripped from the carrier fingers. The die includes a plurality of formed channels which receive the non-cylindrical sleeves and force them into a substantially cylindrical configuration as they are stripped into respective channels.
