WORKING OF WOOD NOT PROVIDED FOR IN SUBCLASSES B27B TO B27L; MANUFACTURE OF SPECIFIC WOODEN ARTICLES
Working of wood not provided for in subclasses B27B to B27L, e.g. by stretching
Definition statement
This group covers:

Stretching wood, breaking or snapping wood, stress relief, cutting and slicing (machines for cutting up wood by knife action without following the grain).

Relationship between large subject matter areas

This group is for the classification of woodworking techniques/treatments/machines not already provided for in subclasses B27B to B27L.

Informative references
Attention is drawn to the following places, which may be of interest for search:

Riving blades

Solid material comminution or disintegration, for apparatuses for reducing wood to non-shaped particles

{Mechanical surface treatment}
Definition statement
This subgroup covers:

Mechanical surface treatment including cutting or shaping particularly of plural discrete diverse cutting operations, the operations including slicing, slitting, chipping, planing sanding etc. Particularly for producing an aged or antique look to the worked surface.

{for preparation of impregnation by deep incising}
Definition statement
This subgroup covers:

Machines for preparatory processing by incisions in wood prior to impregnation, includes log punching (machines intended to pierce radially through a log).

by compressing
Definition statement
This subgroup covers:

Shaping by applying pressure.

by punching out
Definition statement
This subgroup covers:

Machines including a cutter for cutting out pieces or simply cutting holes by mere punching action.

Informative references
Attention is drawn to the following places, which may be of interest for search:

For punching out defects.

by burning or charring, e.g. cutting with hot wire (as surface treatment B44B{ cutting synthetic materials with heated tools B26F 3/06 to B26F 3/12})
Definition statement
This subgroup covers:

Processes including applying heat to the tool or wooden part.

References relevant to classification in this group
This subgroup does not cover:

As surface treatment

Cutting synthetic materials with heating tools

by multi-step processes
Definition statement
This subgroup covers:

Machines for carrying out a number of different machining steps, usually taking place in sequence along a workpiece or machine tool transfer direction.

Machines including a first structure for performing an operation of this class on a workpiece and including a second structure for performing a second, distinct, operation on the same or a second workpiece.

Manufacture or reconditioning of specific semi-finished or finished articles (features of copying devices B23Q; manufacture of plywood or veneer, shaping plywood or veneer into articles B27D; of central layers for plywood B27D 1/06; nailing or stapling machines in general B27F 7/00; of elements for cooperage or wheel making B27H{presses therefor B27D 3/00})
References relevant to classification in this group

Definition statement
This subgroup covers:

The manufacture of assembled wooden elements (side by side, end to end or both, corner jointing etc.) Products per se are in the product groups where they exist.

References relevant to classification in this group
This subgroup does not cover:

of furniture {or of doors(B27D 5/003 takes precedence)}
Definition statement
This subgroup covers:

The manufacture of assembled wooden elements to form furniture, doors, window frames, blinds, sills or drawers. Furniture or frame presses (frame presses also in B27M 3/0013). Products per se are in the product groups.

Relationship between large subject matter areas

For the classification of doors, B27D 5/003 takes precedence.
