Der in der Krimpstation 8 an einem Leiter 9 zu befestigende Kontakt a wird dabei mittels des die einzelnen Kontakte a eines Kontaktbandes 1a miteinander verbindenden Kontaktträgerstreifens 1a' in eine im Verschiebeweg 10 eines Kontaktergreifungsteiles 11 einer ersten Kontakttransfereinheit 12 sich befindende Kontaktergreifungsposition 13a (Fig. 4c) bewegt. In der letzteren wird der der Krimpstation 8 zuzuführende Kontakt a über seinen ihm zugeordneten Kontaktträgerstreifenabschnitt 1a" (siehe Fig. 4b und 5) in Richtung der Längsachse B des zugeordneten Kontaktes a gesehen unter Freilassung zweier seitlicher Aussenabschnitte 14 und 14' (siehe Figuren 5 und 6) des Kontaktträgerstreifenabschnittes 1a" mittels des Kontaktergreifungsteiles 11 in seinem Mittelbereich erfasst, und danach mittels einer Abtrenneinheit 15 vom übrigen, rückwärtigen Teil des Kontaktträgerstreifens 1a' abgetrennt. Um eine derartige mittige Erfassung des Kontaktträgerstreifenabschnittes durch den Kontaktergreifungsteil 11 unabhängig von der bei unterschiedlichen Kontaktbändern 1a bis 1f unterschiedlichen Länge des jeweiligen Kontaktträgerstreifenabschnittes zu ermöglichen, werden die einzelnen Kontaktbandabschnitte jeweils so weit in die zugeordnete Kontaktergreifungsposition vorwärtsbewegt, bis deren Längsachse B (Fig. 5) sich genau mittig im Verschiebeweg 10, d.h. der Kontaktergreifungsposition des Kontaktergreifungsteiles 11, befindet. Somit befinden sich die Kontaktergreifungspositionen sämtlicher Kontaktzufuhrstationen 2a bis 2f unabhängig von der Grösse der zuzuführenden Kontakte a bis f auf einer gemeinsamen Linie 10. The feed means 6 are in a known manner actuated by means of pneumatic cylinders 7.
