Abstract
An apparatus ( ) for securing a fastening strip ( ) to a web ( ) of packaging material comprises an anvil ( ) which defines a support surface for the web. The support surface has an elongate recess ( ) for receiving the fastening strip. There is a moveable sealing device ( ) disposed opposite and below the support surface and a retractable support element ( ) disposed between the support surface and sealing device. A feeding arrangement feeds the fastening strip along the recess and between the support element and the support surface arrangement. Suction is applied via a vacuum chamber ( ) to hold the fastening strip in the recess and permit the support element to be retracted to a position which permits the sealing device to move the web into engagement with the support surface and the fastening strip with the fastening strip received in the recess to permit sealing of the fastening strip to the web.
