摘要:
The method comprises the steps of infiltrating water through the edge of the felt material, freezing and hardening the edge of the felt material, adjusting the angle of a cutting device, running the cutting device over the edge of the felt material with a given inclination and cutting the edge of the felt material at a fixed angle. The method may be carried out with a device comprising a worktable 1 to receive and support the edge of the felt material F, a running guide 11 provided along the edge of the felt material on the worktable, and a uniting or mounting device 20 which supports a cutting device running along the edge of the felt material at a given angle and slides freely on the worktable. The cutting device is provided at the front of the felt material to cut a soaked edge of the felt material with an even chamfer at a given angle after freezing the edge of the felt material by jetting out freezing gas against the edge.

摘要:
A welding device comprising a body (1) having a cylindrical portion (3) and an integral gripping portion (2) extending away from the cylindrical portion. A welding head (10) is provided at one end of the cylindrical portion. The welding head is angularly displaceable relative to the cylindrical portion about the longitudinal axis of the cylindrical portion and supports an ultrasonic transducer (22) and an anvil (23) cooperable with the transducer. The transducer and anvil are relatively movable towards one another to pinch an object (T) to be welded therebetween. A pulling device (25) operable by a trigger is provided for pulling the transducer and the anvil towards one another and a battery pack (B) is releasably attached to the gripping portion.
