Title: BONDING APPARATUS
Abstract:
The present disclosure relates to apparatuses for mechanically modifying substrates. The apparatuses include a bonding roll (107) and an anvil roll (106). The bonding roll (107) includes a pattern element (118). The pattern element (118) and associated pattern surface (120) do not extend completely around the circumference of the bonding roll (107). As such, the bonding roll (107) also includes one or more bearer rings (128) that engage the anvil roll (106) during portions of the bonding roll (107) rotation where the pattern element (118) is not in engagement with the anvil roll (106). The pattern element (118) and bearer rings (128) herein are configured to help reduce vibrations in the anvil roll (106) and/or bonding roll (107) caused by the alternating engagements of the pattern surface (120) and bearer rings (128) with the anvil roll (106) during rotation.
