A die for dispensing a fluid onto a substrate, wherein the die has an movable lip adjacent a fixed lip to form a die opening therebetween. An actuator is mechanically connected to the movable lip and is operable to automatically move the movable lip with respect to the fixed lip in association with a fluid dispensing process, thereby changing a volume of the die opening. The adjustable die is often a slot die and is used with a fluid dispensing valve having an upstream valve ball. The actuator can be an electromechanical actuator such as a piezoelectric actuator or a fluid operated actuator.

Adjustable die for a fluid dispenser and method

A method and apparatus for dispensing material, including adhesives, onto a substrate, including boxes and cartoons. A first and second dispenser are either operated in a dispense and standby mode or both dispense at least a portion of the dispensed pattern. The detection of a failure of one of the dispensing guns causes the other gun to dispense the complete pattern while de-activating the failed gun thereby maintaining production.

Method and apparatus for dispensing material onto substrates

An apparatus for use in supplying thermoplastic material such as hot melt adhesive from containers includes an apparatus for detecting and indicating when thermoplastic material or adhesive has moved out the container such that the container may be removed from the apparatus. Both force responsive and temperature responsive indicators are disclosed, along with various signalling devices, to inform an operator when the container may be removed leaving the material within the apparatus.
