Abstract
A method for dry production of a sliding layer on a flexible backing, in particular a backing that includes a textile or an abrasive backing, includes at least the following. A binder, or more particularly an adhesive such as a hot-applied adhesive or a hotmelt, is applied to a flexible backing. The binder is applied in dry form, such as via scattering, and is joined to the backing via exposure to heat to form a sliding layer on the backing and to hold the sliding layer at least one of on and in the backing. A lubricant, or more particularly a lubricant that includes graphite or PTFE, is applied to at least one of the backing and the binder.
Claims30
A method for producing a lining for a sanding pad configured to slidingly engage an abrasive, the method comprising:
- forming a sliding layer via a dry production process that includes:
- applying a binder in dry form to a first face of a flexible backing;
- joining the binder to the flexible backing via exposure to heat to form a sliding layer on the flexible backing, and to hold the sliding layer at least one of in and on the flexible backing;
- and
- applying a lubricant to at least one of the flexible backing and the binder;
- wherein:
- a second face of the flexible backing opposite the first face is configured to connect to an accommodation face of a sanding pad, such that the flexible backing forms a lining on the accommodation face and such that the sliding layer is configured to slidingly engage an abrasive supported by the sanding pad;
- and
- the lining is free from abrasive material.
A method of using a lining backing that includes an abrasive layer disposed on a first backing side, and a sliding layer disposed on a second backing side facing away from the first backing side, the sliding layer including (i) a first layer including a lubricant or a binder and the lubricant (ii) a second layer including the binder and the lubricant and (iii) a third layer including the lubricant and free from the binder, the binder applied to the backing in dry form and joined to and held on the backing via exposure to heat, and the lubricant applied to at least one of the backing and the binder, the method comprising:
- separably joining the lining backing to a sliding mechanism embodied as a sanding pad.
A method for dry production of a sliding layer on a flexible backing, comprising:
- applying a binder in dry form to a flexible backing and applying a lubricant to at least one of the flexible backing and the binder to form a sliding layer on the flexible backing, wherein forming the sliding layer includes:
- forming a first layer of the sliding layer by either:
- applying a mixture of the binder and the lubricant to the flexible backing to form a first layer that consists of the binder and the lubricant;
- or
- applying the lubricant to the flexible backing so as to form a first layer of the sliding layer that consists of the lubricant
- forming a second layer of the sliding layer by either (i) separately applying the binder and the lubricant to the first layer or (ii) applying a mixture of the binder and the lubricant to the first layer, such that the second layer consists of the binder and the lubricant;
- and
- forming a third layer of the sliding layer by applying the lubricant to the second layer, such that the third layer consists of the lubricant;
- and
- joining the binder to the flexible backing via exposure to heat to form a sliding layer on the flexible backing, and to hold the sliding layer at least one of in and on the flexible backing.
A backing for abrasive machining of a workpiece, comprising:
- a sliding layer disposed on a first backing side, the sliding layer consisting of a binder and a lubricant, the sliding layer including:
- a first layer including the lubricant or the binder and the lubricant;
- a second layer including the binder and the lubricant;
- and
- a third layer including the lubricant and free of the binder;
- wherein the binder was applied to the backing in dry form, and was joined to and held on the backing via exposure to heat, and the lubricant was applied to at least one of the backing and the binder.
