  • Apparatus for bonding a tear tape to a web of material
    Patent number: 5411625
    Abstract: An apparatus for bonding a tear tape (10) to a web of material is disclosed. In the packaging art, tear tapes (10) are attached to webs of film in order to create a tear-open aid in packs made of film or with the aid of the film. The tear tape (10) is bonded to the web of material (11) by the application of heat and pressure while the web of material (11) is conveyed with the tear tape (10) over a deflecting roller or sealing roller (12). The sealing roller (12) forms a heating ring (17) which is heated for the transfer of heat and pressure to the web of material (11), but which is thermally insulated from the remaining part of the sealing roller. The sealing roller (12) is formed from several parts. In particular, it is formed from two part rollers (15, 16) and the heating ring (17) which is located between these part rollers with gaps (38, 39).
