Abstract

The invention relates to a press-on element 1 for an abrasive belt 30 , in particular for wide belt grinding machines, consisting at least of a backing material 10 with a padding 3 and a sliding layer 4 . To clearly improve the grinding results, a method and a press-on element 1 based thereon are employed which permits an additional cooling of the padding 3 and thereby the abrasive belt 30 . The press-on element 1 here substantially consists of a padding 3 consisting of a spacer fabric. The spacer fabric is manufactured from two loosely woven textile surfaces which are connected to each other by pile threads so that the cooling medium can flow through the padding 3.

Claims (28)

1 . A press-on element ( 1 ) for a wide belt grinding machine comprising:

a backing material ( 10 ) with a padding ( 3 ), and

a sliding layer ( 4 ),

wherein the padding ( 3 ) comprises a spacer fabric, and

wherein a cooling medium penetrates, via a first chamber of a sanding pad mounting, through at least one first passage, into the spacer fabric and, after the cooling medium has flowed through the spacer fabric, exits through at least one second passage into a further chamber of the sanding pad mounting.

2 . The press-on element ( 1 ) according to claim 1 , wherein the padding ( 3 ) consists of the spacer fabric.

3 . The press-on element ( 1 ) according to claim 1 , wherein the spacer fabric comprises at least two woven textile surfaces ( 11 , 12 ), and/or the two woven textile surfaces ( 11 , 12 ) are connected to each other by pile threads.

4 . The press-on element ( 1 ) according to claim 1 , wherein the spacer fabric has a thickness tolerance of +/−5 hundredth of a millimeter.

5 . The press-on element ( 1 ) according to claim 1 , wherein the spacer fabric comprises moisture-stable synthetic fibers.

6 . The press-on element ( 1 ) according to claim 1 , wherein a compressive strength of the padding ( 3 ) is determined by a number of pile threads, a structure, a length and/or a thickness.

7 . The press-on element ( 1 ) according to claim 6 , wherein the spacer fabric is penetrated by the cooling medium, and/or a gas is employed as the cooling medium.

8 . The press-on element ( 1 ) according to claim 1 , wherein the cooling medium flows through the spacer fabric in a longitudinal and/or a transverse direction.

9 . A method for grinding wood or wood substitute materials, comprising:

providing the press-on element ( 1 ) according to claim 1 ; and

cooling the press-on element ( 1 ) during a grinding process by the cooling medium which flows through the padding ( 3 ).

10 . The method according to claim 9 , wherein the cooling medium is supplied and discharged via the sanding pad mounting ( 2 ).

11 . The method according to claim 9 , wherein a circulation or flow of the cooling medium is effected via the sanding pad mounting ( 2 ) through the padding.

12 . The method according to claim 9 , wherein the cooling medium is supplied and discharged under pressure.

13 . The method according to claim 9 , comprising:

providing a constant flow of the cooling medium through the first chamber ( 14 ) of the sanding pad mounting ( 2 ) into the spacer fabric, and

discharging the cooling medium through the further chamber ( 16 ) of the sanding pad mounting ( 2 ).

14 . The press-on element ( 1 ) according to claim 1 , wherein the padding ( 3 ) comprises the spacer fabric in a longitudinal and/or a transverse direction which is hemmed by edge strips of another padding material in the longitudinal and/or the transverse direction.

15 . A press-on element for a wide belt grinding machine, comprising:

a backing material with a padding that at least partially comprises a spacer fabric;

a sliding layer; and

a sanding pad mounting having:

at least one first chamber from which a cooling medium is supplied through at least one passage in the backing material into the spacer fabric, and

at least one second chamber through which the cooling medium is discharged from the spacer fabric through a further at least one passage in the backing material.
