Abstract: An apparatus and method for closing a perform shell about a wound film spool or similar object has a jaw assemblage having a pair of jaw members. The jaw members have a predetermined configuration for receiving and then closing a preform shell about the object. Jaw members are connected by a series of pivot members and connecting drive links. The drive link precisely controls the movements of connecting links supporting the jaw members.

Abstract: An apparatus for closing a preform shell about a wound film spool or similar object has a jaw assemblage having a pair of jaw members. The jaw members have a predetermined configuration for receiving and then closing a preform shell about the object. Jaw members are connected by a series of pivot members and connecting drive links. Drive means precisely controls the movements of connecting links supporting the jaw members thereby causing the jaw members to open and close.

Abstract: Web spooling equipment has an improved means for closing a preform shell about a film spool or similar object. The improved equipment utilizes a rotatably mounted jaw assemblage having a pair of jaw members for opening to receive a preform shell enclosing a wound spool or similar object and then closing about the preform shell to form a near perfect round cylindrical shape. Precision movements of the jaw assemblage are governed by connecting links and a series of pivot members connecting the jaw members and connecting links. The closed preform shell is then transferred downstream of the closing step by the jaw assemblage for independent treatment.
