Force is applied by a pressure bar (6) and roller (7). These act independently and in succession on the band. They can be swung between operational and idling positions. The pressing bar attaches the upper layer of composite forming part of the band onto the surface of application, whilst the pressure roller forces the composite against the corresponding surface, effecting consolidation. Preferred features: Cylinders swing the bar and roller, independently on their supports, between working and idling positions. Other cylinders come into action to press the roller forcibly against the application surface, in the working position. On the way to the feed zone, the band (3) passes over guides fed with air under pressure to prevent friction. They can be altered in width by actuators, to accommodate different widths of band. They can be moved laterally for central alignment during application. The feed reel mounting can be moved axially by an actuator for centralization. A cutting mechanism is incorporated, the blade carriers and mechanism are further detailed. The design eliminates play in head movement. |
