Abstract:
A web coating apparatus (20) includes a supply roll (26) of web (22) and a wind-up spindle (86) for receiving a discrete length of the web (22). Fluid is discharged from a coating die (92) in a direction toward the wind-up spindle (86) to coat the web (22) as the web (22) is wound about the wind-up spindle (86). A variable speed pump (108) directs fluid through the coating die (92) at flow rate that is proportional to the speed of advancement of the web (22). The apparatus (20) is particularly useful for coating discrete lengths of orthopedic splinting and casting tape that is packaged for single patient use.
Abstract:
Die erfindungsgemässe Fördervorrichtung zum Fördern eines viskosen Materials aus einem Behälter umfasst eine in den Behälter (8) einsetzbare Folgeplatte (7) und eine Pumpe (6), mit der das viskose Material (9) durch die Folgeplatte (7) hindurch förderbar ist. Zudem ist eine Messkammer (31) zur Aufnahme einer Messprobe (19) des viskosen Materials (9) vorgesehen. Die Messkammer (31) weist dazu eine verschliessbare Material-Einlassöffnung (31.1; 85.1) auf. Von der Messkammer (31) führt eine verschliessbare Entsorgungsleitung (36) weg. Des Weiteren ist eine von der Messkammer (31) über die Folgeplatte (7) in den Behälter (8) führende verschliessbare Material-Rückführleitung (37) vorgesehen. Die Fördervorrichtung umfasst auch eine Steuerung (22), die derart ausgebildet und betreibbar ist, dass sie bei mehreren Messproben (19) jeweils deren Kompressibilität ermittelt. Abhängig von der ermittelten Kompressibilität, gibt die Steuerung (22) die Entsorgungsleitung (36) oder die Material-Rückführleitung (37) für die in der Messkammer (31) befindliche Messprobe (19) frei.
Abstract:
A hot melt adhesive system includes an adhesive supply for receiving solid or semi-solid hot melt adhesive, and a heater associated with the adhesive supply for melting the solid or semi-solid hot melt adhesive into liquid hot melt adhesive. An adhesive tracking system monitors an output of the liquid hot melt adhesive, and includes a flow meter having a flow inlet and a flow outlet. The flow meter measures an amount of the adhesive flowing out of the flow outlet. A product detector may be used to sense a presence of a product to which the adhesive is applied. A controller then determines the total amount of the liquid adhesive dispensed and the average amount of liquid adhesive dispensed per product.

Abstract:
A robot arm mounted apparatus for high speed streaming of high viscosity, two-part adhesive onto a workpiece. The apparatus employs a shortened, temperature-conditioned mixing tube (38) and a compact, end effector package of dispense metering equipment associated directly with the mixing tube (38) on the end of the robot arm, rather than mounted remotely as in prior art systems. In a preferred form a pressurized cylinder (60), displacement rods (64) and chambers, dispense metering valves (66) and shortened, temperature-conditioned mixing tube (38) are connected to one another directly in serial fashion on the end of the robot arm. The mixing tube (38) is preferably modified with a removable, damage-resistant nozzle (41) designed especially for streaming.
Abstract:
A system (10) for dispensing hot melt adhesives, comprising an adhesive dispenser (78) including a fluid passage (100) leading to an outlet (102). The system further comprises a supply conduit (72) fluidly connected to the fluid passage (100) and a feeding mechanism (46) configured to feed an elongate, flexible element of solid adhesive (12) into the supply conduit. The system further comprises a first heating element (82) positioned along at least a portion of the supply conduit (72) to melt a portion of the elongate, flexible element being fed into the supply conduit and thereby form a supply of liquid adhesive within the supply conduit.
Abstract:
An ejector (1) for jetting droplets (22) of viscous media onto a substrate (23) is disclosed. The ejector comprises a jetting nozzle (2) having a nozzle space (3) and a nozzle outlet (4), and an impacting device (6) for impacting a volume of the viscous medium in the nozzle space such that droplets of viscous medium is jetted from the nozzle space through the nozzle outlet towards the substrate. The ejector also comprise a sensor arrangement (5) arranged after the jetting nozzle in the jetting direction, wherein the sensor arrangement is adapted to detect a jetted droplet of viscous medium passing thereby.
