Abstract
An apparatus for the conjoint gripping of bobbins by means of pins or spigots formed of a rigid material, mounted at a support or carrier, and insertable into the bobbins. An expansible hose or tube member extends lengthwise of the support, this hose member when subjected to an increased internal pressure serving to press the bobbins against the pins or pin members inserted therein. This known apparatus has the advantage that there does not occur damage to the entering pin members, nor does there arise permanent deformation or destruction thereof. Yet, such apparatus possesses the shortcomings that the seized bobbins, when pressed against the pin members, are not positioned with sufficient accuracy in a direction parallel to the longitudinal direction of the support. The invention avoids such drawback in that, there are provided two straight edges at each pin member at the side thereof confronting the hose member, such too straight edges extending in the longitudinal direction of the related pin member and serving as contact surfaces for the bobbin pressed thereagainst.
