Abstract

A work table having longitudinal and transverse cutter guide rails and a removable cutter. The cutter cooperates with linear knives on a longitudinal edge and on a lateral edge of the work table for making longitudinal and transverse cuts to form blanks from sheet stock. A roller knife on the cutter cooperates with linear knives on transverse and lateral edges of the work table to cut coil stock. The longitudinal cutter guide rail is provided with cam clamps that flex the beam to securely clamp sheet stock between the upper beam and the table top when longitudinal cuts are made. Grid lines and template instructions may be provided to assist workers in measuring and laying out blanks of sheet stock. Sheet stock may be supplied from a coil that is retained in a coil holder either on the work table or adjacent to the work table on a separate stand.

Claims18

Dependent claims

A portable work table for cutting a piece of sheet material to be fabricated comprising:

a stand;
a table top supported on the stand, the table top having a front longitudinally extending edge, a rear longitudinally extending edge, a first transversely extending edge and a second transversely extending edge;
a transversely extending guide rail secured proximate the first transversely extending edge of the table, the guide rail being shifted between a first position wherein the guide rail is spaced above the piece of sheet material on the table and a second position wherein the guide rail is held at a position for clamping the piece of sheet material against the table;
a longitudinally extending guide rail secured proximate the front longitudinally extending edge of the table top, the longitudinally extending guide rail being shifted between a first position wherein the longitudinally extending guide rail is spaced above the piece of sheet material on the table and a second position wherein the longitudinally extending guide rail is held at a position for clamping the piece of sheet material against the table;
and
a removable cutter having a plurality of rolling elements that support the cutter on either of the guide rails, the cutter having a knife disposed to cut the piece of sheet material supported on the table by coacting with either the front longitudinally extending edge or the first transversely extending edge of the table;
wherein the longitudinally extending guide rail and the transversely extending guide rail are independently moveable.
