Web lifter and/or stabilizer and method of lifting and/or stabilizing a travelling web and for coating a web. The device creates a web hold down force via a negative pressure slot at its exit side, which draws the web down against the surface on the entry side. The device can be actuated to move the web relative to a slot die coater off the die lips and stop the application of slurry to the web, thereby creating uncoated regions on the web surface. The device can then be actuated to move the web back into contact with the coater to start the application of slurry to the web, thereby creating coated regions on the web surface. Web lifting can be accomplished by rotating the device in first and second directions to lift the web off of the slot die coater and return the web back into contact with the coater.

Systems and methods for tuning a closed-loop controller for a hot melt liquid dispensing system are disclosed. In an example method, based on a set temperature setpoint, the hot melt liquid dispensing system is maintained at a steady state with respect to a temperature process variable and a heater duty cycle control variable. The heater duty cycle control variable is brought to a sustained oscillation. An amplitude and an ultimate period are determined. An ultimate gain is determining based on the step value and the amplitude. A proportional, integral, or derivative constant is determined based the ultimate period and/or ultimate gain. The closed-loop controller is implemented using the proportional, integral, or derivative constant.

In one example, a melter has a housing, a heater, a vent, and a filter medium. The housing defines a receiving space that supports adhesive therein. The heater heats the receiving space of the housing to melt the adhesive. The melter defines an adhesive inlet therein that receives adhesive carried by a transport supply gas into the receiving space. The vent extends through a wall of the melter and permits the transport supply gas to escape from the melter. The filter medium is supported in the vent to capture particulates from the transport supply gas escaping the receiving space, and is positioned relative to the receiving space such that heat from the receiving space causes the particulates captured by the filter medium to melt and fall into the receiving space.

The first and second clamps secure the nozzle to the body of the manifold. The body of the manifold has a first contact surface that engages the first clamp and a second contact surface that engages the second clamp and the nozzle, where the second contact surface is angularly offset from the first contact surface.

A supply device includes a collect tank which collects a process liquid from a substrate processing device and heats the collected liquid, and a supply tank connected to the collect tank and which supplies, to the substrate processing device, the process liquid heated in the collect tank. The collect tank includes a collect container that stores the process liquid, a first dividing plate that divides the collect container into a first region where the process liquid is introduced from the substrate processing device, and a second region that introduces the process liquid to the supply tank, piping that feeds, to the second region, the process liquid introduced in the first region, a first heater provided on a path through the piping and which heats the process liquid, and feed piping that feeds, to the supply tank, the process liquid in the second region and heated by the first heater.

A flexible map with application data identifiers for PLC communications is described. An example method comprises receiving a first user input indicative of a selection of a parameter from a plurality of parameters associated with an adhesive dispensing system (614). The parameter is subject to data exchange between a controller (616) of the adhesive dispensing system (614) and an associated programmable logic controller (610). A second user input is received that is indicative of a memory space location in a memory space of the controller (616). A custom data map is generated that is indicative of an association between the selected parameter and the memory space location.
