A plastic welding machine for welding plastic parts together is capable of controlling the weld force vector in both magnitude and direction.

A dual roll fabric welding or seaming machine is configured to seam pieces of sheet material to one another as the pieces move downstream. The machine includes modular gantries and various actor devices which may be readily mounted on any of the gantries to interact with the moving sheet material to achieve various functions, such as seaming pieces of sheet material together, forming hems, applying grommets to the sheet material, printing on the sheet material, connecting reinforcement strips or ropes to the sheet material and cutting the sheet material.

A method for producing a receptacle which is closed by a sheet by transmission laser welding, and to an apparatus suitable to carry out same. The method and the apparatus are configured in such a way that a weld seam is formed between the wall structure of the receptacle and the sheet so as to be wider than the end faces of the wall structure.

Disclosed herein is a head fixture for adhesively bonding a part of a golf club head to a body of the golf club head. The head fixture includes a bottom portion, including a body retainer, and a top portion, selectively attachable to the bottom portion and including pressure applicators spaced apart about the top portion. Each one of the pressure applicators comprises a ratcheting mechanism and a ribbed shaft engaged with the ratcheting mechanism such that, when the top portion is selectively attached to the bottom portion, the ribbed shaft is movable away from the body retainer into a position, associated with a pressure applied to the part of the golf club head by the ribbed shaft, and the ribbed shaft is non-movably fixable, relative to the body retainer, in the position.
