Abstract
The invention relates to a foaming device (1) which has a foaming unit (2) with a foaming chamber (17), said foaming chamber comprising mechanical foaming means (15, 19) which are contained inside the chamber and by means of which at least three components that are fed to the foaming chamber (17) can be mixed. At least one adhesive, a gaseous foaming medium, and a free flowing diluent are used as the components in order to produce an adhesive foam. Adjusting means (25) are provided in order to adjust the ratio of the individual components to one another in order to influence the properties of the adhesive foam.
Claims17
A foaming apparatus (1) comprising a foaming unit (2) having a foaming chamber (17) having mechanical foaming means (15, 19) contained therein, with which means at least three components delivered to the foaming chambers (17) are mixable, wherein at least an adhesive, a gaseous foaming medium, and a flowable diluent are utilized as components in order to output an adhesive foam, wherein adjusting means (25) are provided for adjusting the ratio of the individual components with respect to one another in order to influence the properties of the adhesive foam.
An apparatus for foaming adhesive (1) a foaming unit (2) having a mixing and foaming chamber (17), said chamber comprising a mechanical foaming means (15, 19) therein, and at least three component delivery units to supply the components to the foaming chambers (17),
- wherein the first component is an adhesive, second component is a gaseous foaming medium, and a third component is a diluent;
- and
- wherein each of the delivery units comprise an independent controller (25) to adjust the ratio of each of the components supplied to the chamber.
An apparatus for making foamed adhesive, comprising:
- a foaming unit having a mixing and foaming chamber, said chamber comprising a mechanical foaming means therein;
- a first component delivery unit to supply unfoamed adhesive to the foaming chamber, the first component delivery unit comprising a first controller;
- a second component delivery unit to supply gaseous foaming medium to the foaming chamber, the second component delivery unit comprising a second controller;
- a third component delivery unit to supply diluent to the foaming chamber, the third component delivery unit comprising a third controller;
- wherein each controller can be individually adjusted to control a ratio of unfoamed adhesive and gaseous foaming medium and diluent supplied to the foaming chamber, said foamed adhesive having properties influenced by the ratio of unfoamed adhesive and gaseous foaming medium and diluent.
