Apparatus (50) for spin closing an open end (30) of a tube (12) of a suspension strut comprising a throughbore (52) having a longitudinal axis (A); a first pair of rollers (54), each roller of the first pair being rotatably mounted in a bore (60) opening into the throughbore, having a contact surface (78) at a first predetermined angle to the longitudinal axis and which extends into the throughbore, and being biased such that the contact surface can retract from the throughbore against the action of biasing means (68); and a second pair of rollers (56), each roller of the second pair being rotatably mounted in a bore (72) opening into the throughbore, and having a contact surface (80) at a second predetermined angle to the longitudinal axis and which extends into the throughbore; wherein the second predetermined angle is greater than the first predetermined angle; and wherein the first pair of rollers is offset (H) from the second pair of rollers along the longitudinal axis such that, on insertion, the open end of the tube of the suspension strut will make contact with the contact surfaces of the first pair of rollers before contacting the contact surfaces of the second pair of rollers. Allows spin closing of the open end of a suspension strut at a single workstation. <MATH> <MATH> |
