Abstract

PURPOSE:To utilize conventional assembling equipments in their entirety by equally spacing adjoining tabs in the longitudinal direction where each pellet is fixed. CONSTITUTION:Leeds 9 to 14 out of a set of multiple leeds which are supported by a leed frame supporter 4, are used as leeds of a package 1. Among these leeds, the reeds 10 and 13 are formed their tips wider and are assigned as tabs 5a and 5b where pellets are fixed. The distance between these tabs 5a and 5b is set equal to 1/2 of a longitudinal frame pitch L of the package 1, and is also equal to the span between tabs 5c and 5d being located on the longitudinal line of the frame. As a result, the leed frame can be fed during assembling in the longitudinal direction with the equal pitch of L/2, thus eliminating special equipments which have different pitches. Consequently, the conventional equipments can be used in their entirety.
