Abstract:
The mechanism of making an anti-slip handle having a pair of opposed faces and having a gripping portion on each face which comprises means for forming a plurality of grooves on one face of the gripping portion of the handle comprising means for forming a first set of grooves in one direction and means for forming a second set of said grooves in the other direction whereby the two sets of grooves intersect each other to form a cross-hatched groove network, said grooves in each set are formed parallel to each other, means for moving a groove-forming means and said handle relative to each other in one direction to form said first set of grooves, means for moving a groove-forming means and said handle relative to each other in the other direction to form said second set of grooves, said moving means moves the groove-forming means in parallel passes in one direction to form the first set of grooves and thereafter moves the groove-forming means in parallel passes in the opposite direction to form the second set of grooves at an angle to the first set of grooves, means for forming a plurality of grooves on the opposite face of said handle which comprises means for turning the handle and the groove-forming means relative to each other to a position where the opposite face of the handle and the groove-forming means face each other, means for forming a plurality of grooves on the opposite face of the gripping portion of the handle comprising means for forming a first set of grooves in one direction and means for forming a second set of said grooves in the other direction whereby the two sets of grooves intersect each other to form a cross-hatched groove network, said grooves in each set are formed parallel to each other, means for moving a groove-forming means and said handle relative to each other in one direction to form said first set of grooves, means for moving the groove-forming means and said handle relative to each other in the other direction to form said second set of grooves, said moving means moves the groove-forming means in parallel passes in one direction to form the first set of grooves and thereafter moves the groove-forming means in parallel passes in the opposite direction to form the second set of grooves at an angle to the first set of grooves.
