Fluid e.g. hot melt adhesive, dispensing device, for foil or layer-shaped substrate e.g. label, has valve with rotatable body to selectively interrupt and release fluid flow, and nozzle arrangement communicating with supply channel

摘要

The device has a fluid supply channel that is formed in a base (14) and is connected with a fluid source (20) to supply fluid. A valve (33) is provided with a valve body (34) that is rotatable for selectively interrupting or releasing the fluid flow. A nozzle arrangement (22) communicates with the supply channel and includes an outlet for dispensing the fluid. The valve body has a flat area and is cylindrical in shape. A lever is detachably connected with the valve body for adjusting the body.
