Abstract:

An apparatus and method for forming an endless spiral wound abrasive article and the resulting article. The apparatus includes first and second spaced-apart hubs, configured so that a portion of first and second webs passing between the first hub and the second hub is oriented substantially in a plane which remains stationery even if a position of a hub is changed. The apparatus further includes winders and a web joiner. The method includes providing a second web which includes an adhesive disposed on a first surface and a liner releasably affixed to the adhesive. The method includes removing the liner from the second web before positioning the second web adjacent the first web. The first and second webs are wound about the first and second hubs to form a spiral wound article having a desired circumference.

US Classification:

111118

Abstract:

The present invention relates to a soil injection apparatus in which a probe having on insertion tip is inserted into the soil. A pair of probe guide assemblies are positioned adjacent each side of the probe to provide stability of the probe and prevent breaking of the probe. A probe hydraulic system extends and retracts the probe from the soil. A liquid pumping system pumps liquid into an outlet of the probe after insertion of the probe into the soil. A control system activates the probe hydraulic system and liquid pumping system. Preferably, a switch is used to activate the pumping system to pump liquid into the soil after the probe has been inserted a predetermined depth into the soil. The soil injection apparatus can be attached to a self-propelled vehicle. A carrier can be attached to the vehicle for holding debris removed from the soil injection site.
