Application No. 09/702,981
34. A cushioning conversion machine comprising a conversion assembly
which converts a sheet stock material into a three dimensional cushioning
product and a stock supply assembly which supplies the stock-material to the
conversion assembly;
the conversion assembly including a forming assembly which inwardly
turns lateral regions of the stock material as the stock material travels
therethrough in a downstream direction;
the stock supply assembly including a stock-dispensing device which
dispenses the multi-ply stock material from a continuous sheet thereof and a
constant-entry device which determines an entry point of the stock material
upstream of the conversion assembly;
the constant-entry device also temporarily functioning as a force
dampening device during a high tension situation, moving from a normal
operating position to a tension yielding position, and then automatically returning
to its normal operating position once the high tension situation is resolved.
118. A cushioning conversion machine comprising a conversion assembly
which converts a sheet stock material into a three dimensional cushioning
product and a constant-entry device which determines an entry point of the stock
material upstream of the conversion assembly; the constant-entry device biased
to an operating position and movable between the operating position and a
tension yielding position, thereby temporarily functioning as a force dampening
device during a high tension situation and automatically returning to the
operating position once the high tension situation is resolved.
The teachings of the applied prior art
Simmons
Simmons' invention relates generally to cushioning conversion machines and
more particularly to improvements in the mechanisms for feeding material into
such machines for conversion into a dunnage product. Figures 1-5 illustrate a
cushioning conversion machine 10 including an infeed unit 12, a forming assembly 14,
and a cut off (severing) unit 16.
