Problems solved by technology

Air suction can then lead to the fact that, when the coating operation is carried out again, no adhesive flows out of the outlet opening immediately after opening the coating valve, so that the substrate is not provided with adhesive or is only insufficiently provided. with adhesive
This can lead, for example, to insufficient bonding of the spine and consequently subsequent inability to continue processing

Embodiment Construction

[0039] The exemplary embodiment shown in the figures relates to a device 1 for delivering a fluid to a substrate, in particular to a substrate that is movable relative to the device. Different fluids, such as adhesives, hot melt adhesives, can be dispensed and applied to different substrates, such as books, book spines, films or similar objects. The device is used in particular for the planar coating of different substrates with adhesives. It goes without saying that other fluids can be applied to different substrates in a planar manner or in the form of strips or threads.

[0040] especially if figure 1 As shown, the device 1 has a body 2 which is only schematically shown. By means of the main body 2, the device 1 can be positioned on a frame not shown in the desired loading position, so that a substrate (such as a book) can be guided through the device 1 in such a way that the output fluid is applied to the substrate. on the material. Inside the body 2 or on the body 1, ...

Abstract

The apparatus (1) has a base body (2), where a fluid supply passage is connectable to a fluid source for feeding a fluid. A nozzle assembly (4) is designed, which has a distribution channel communicating with the fluid supply passage. A compensation channel stays in fluid communication with the distribution channel to change the volume of fluid intake.

Description

technical field [0001] The invention relates to a device for delivering a fluid onto a substrate, the device having a body, a fluid delivery channel connectable to a fluid source for delivering the fluid, and a nozzle system having a fluid delivery channel connected to the fluid delivery channel. The communicating dispensing channel and the nozzle system have a substantially elongated slit with at least one discharge opening for the output fluid, communicating with the distributing channel, wherein the effective length of the distributing channel that can be filled with fluid can be obtained by means of The closing body that can move in the distribution channel is changed. Background technique [0002] Such devices for dispensing fluids, also known as applicator heads, are used in various industrial fields to apply adhesives, sealants or other liquids in a planar manner on e.g. films, packaging materials, machine parts Or on different substrates such as other workpieces. T...
