"AN IMPROVED CON-
EMIL BUNTZEN, of Lewisham, in the County of Kent.
STRUCTION OF TABLE AND APPARATUS CONNECTED THEREWITH, TO BE USED IN THE
OPERATION OF CUTTING OUT BAGS, SACKS, AND ANALOGOUS ARTICLES."
My Invention relates to the construction of a table and apparatus connected
therewith for use in the operation of cutting lengths of cloth and fabric from the
piece to be made up into bags, or sacks, or analogous articles.
My improved table consists of a framework (of any convenient length and width)
and which is grooved along its top edges to receive the supports of narrow flaps or
leaves which form the top of the table. These flaps or leaves are placed at certain
distances apart, according to the size of the article to be cut, and are held in such
position by clamping screws or other convenient means. The edges of these flaps
or leaves are lined with metal to protect them and prevent their being destroyed
by the knives during the cutting operation.
At one end of the framework is mounted in vertical standards a pair of rollers
which serve as guide rollers, and also as tension rollers, pressure being applied
thereto by a treadle, or in any other convenient manner.
The fabric to be cut is drawn through these guide rollers and over the flaps or
leaves to the other end of the table where the end of the fabric is made fast in any
convenient manner, and weights are placed on the fabric where it passes over the
leaves or flaps to hold it down tight while being cut. These weights I prefer to
mount on a horizontal bar or beam on which they may be slidden or shifted to
correspond with the narrow flaps or leaves.
The horizontal bar or beam inay be supported in brackets attached to the frame-
work of the table, and may be oscillated to raise or lower the weights off or on to the
fabric by a hand lever or any other suitable means. Or the weight beam may be
raised by cords attached thereto and passing over pullies or blocks secured to the
beams or joists of the floor above, or the roof.
The fabric having been drawn between the guide rollers and made fast at the
opposite end of the framework is now ready to be cut. The cutting operation may
be done by hand, or by mechanical means; if the former, the attendant simply runs

page_text: his knife along the edge of the flaps, and the pieces or lengths thus cut off will,
when the weights are raised, fall through the spaces between the flaps or leaves on
to an endless travelling apron which conveys them to the end of the framework,
where they are collected by an attendant.
If the cutting is to be performed by mechanical means the knives or cutters may
be mounted upon a rocking bar carried by brackets at the side of the framework,
and actuated by a lever or other means worked by the attendant, or the knives or
cutters may be mounted in vertical guides and worked by cams or equivalent means
mounted on a horizontal shaft which receives rotary motion from an engine or
other prime mover, the only point to be insisted upon being that they can be
adjusted to correspond with the edges of the flaps or leaves. Travelling clips may
be provided to take hold of the cloth or fabric as it passes through the guide rollers
and draw it forward to the opposite end of the table. The apparatus may be made
automatic by connecting together the various parts by means of gear wheels, and
providing suitable means for throwing the parts in and out of gear as required.
If desired, six or more thicknesses of fabric may be cut at one time, the several
thicknesses being conveyed from piles or rolls of the fabric suitably placed for the
purpose to the guide rollers.
