Abstract: A veneer patching apparatus for removing defects from a plywood veneer (1) includes a defect removing plunger (5), a punch (6) passed through by the removing plunger (5), a patch plunger (8) passing through the punch in alignment and synchronously operating with the removing plunger, elements for feeding the veneer to be patched between the removing plunger, and the punch and elements for feeding patch veneer (2) between the patch plunger and the punch. The stroke length of the removing plunger extends to the level of the patch veneer, and the feeding of the patch veneer is arranged as a continuous web to be fed during the return stroke. The defect to be removed has been arranged to be removed from the apparatus by pressing the defect spot with the removing plunger into the hole made by the patch plunger in the patch veneer.
