Abstract
A machine for pulling paper off of a roll and crumpling the paper increasing the surface area and bulk of the compressible crumpled paper. The crumpled paper is used as packing material, cushioning packaged parts and filling package voids.
Claims15
A paper crumpling machine comprising:
- a floor stand with a first vertical pedestal and a second vertical pedestal;
- said first pedestal supporting a paper crumpler, said paper crumpler having a housing having a front side, a back side, a left side and a right side, said paper crumpler having a feed horn having a rectangular conical feed opening extending inward in flow communication with a driven roller and a first idler roller, said drive roller fixed on an output shaft of a motor, said first idler roller rotatably connected to a rocker plate, said rocker plate pivotally connected to a bottom surface of a pressure plate having an end pivotally connected to a vertical back plate of said paper crumpler and an opposing end of said pressure plate connected to a first end of an extension spring extending downward at a selected angle connected to a pin extending from said back plate said rocker plate having a second idler roller rotatably connected thereto and pressing against said driven roller, said first idler roller and said second idler roller spaced apart on said rocker plate at selected angles with respect to said drive roller, said rocker plate including a diverter plate extending from said first idler roller toward said second idler roller, said paper crumpler having a discharge chute opening facing between said drive roller and said second idler roller,
- said motor attached on a rear side of said back plate, a motor controller attached to said rear side of said back plate, said motor controller having a power on switch, a speed select switch, a paper feed switch, and a foot feed switch electrically connected thereto;
- said second vertical pedestal having a paper feed roll cradle fixed thereto comprising a first plate with a planar surface extending outward at a selected angle above horizontal and a free rolling idler roller spaced apart therefrom, whereby the frictional dampening between said planar surface and a roll of paper serves to keep the speed of unrolling paper under control and prevent said roll of paper from feeding out loose paper while coasting to a stop;
- and
- a feed paper guide hanging down from a bottom edge of said feed horn, said feed paper guide curving upward into a path of feed paper flow and providing frictional dampening against a bottom surface of feed paper.

A paper crumpling apparatus comprising:
- a) a base supporting a paper crumpling machine;
- b) a paper roll cradle mounting to said base, said paper roll cradle including a paper tray with a planar surface extending outward at a selected angle above horizontal and a free rolling idler roller spaced apart therefrom for supporting a roll of said feed paper there between for supplying a ribbon or sheet of said feed paper;
- and
- c) said paper crumpling machine, comprising:
- a motor, a motor controller attaching to a back plate, a power switch, a speed select switch, a paper feed switch, and a foot feed switch electrically connected thereto;
- a feed horn with an opening for receiving a sheet or ribbon of feed paper;
- a first idler roller, a second idler roller, and a drive roller;
- said first idler roller and said second idler roller rotatably connected to a rocker plate and spaced apart positioned above and in contact said drive roller;
- said rocker plate rotatably connecting to a bottom surface of a pressure plate having an end pivotally connecting to a vertical back plate of said paper crumpler, and an opposing end of said pressure plate connecting to a first end of an extension spring and a second end of said extension spring extending downward at a selected angle and connected to a pin extending from said back plate, said spring tensioned to bias said first idler roller against said drive roller;
- said second idler roller rotatably connecting to said rocker plate pressing against said drive roller and said feed paper threaded there between forming a crumpled paper;
- said rocker plate including a diverter plate extending between said first idler roller and said second idler roller and above said drive roller for directing said paper feed between said drive roller and said rear idler roller;
- a crumpled paper discharge chute in alignment with said second idler roller and said drive roller and in flow communication with said crumpled paper;
- and
- means for cutting said crumpled paper exiting said crumpled paper discharge chute.
11 more elements
A method for crumpling paper comprising the steps of:
- feeding a sheet of paper from a roll into a paper crumbling apparatus comprising:
- a support stand extending from a base, said stand including means for adjusting its height;
- a frame pivotally attaching to said support stand;
- said frame including a housing;
- said frame including a generally vertical support plate disposed within said housing;
- said support plate including a first side including an electric motor and means of controlling said motor;
- said support plate including a roller assembly affixed to a second side in cooperative engagement with said electric motor, said roller assembly including a pressure plate pivotally mounting to said second side of said support plate, said pressure plate exerting downward pressure due to biasing means in cooperative engagement therewith mounting to said support plate;
- a rocker plate pivotally mounting below said pressure plate supports said roller assembly;
- said roller assembly including a front idler roller mounting thereto and a rear idler roller spaced apart therefrom, a drive roller spaced apart from and disposed between said rear idler roller and said front idler roller, and a diverter plate mounting to said rocker plate between said rear idler roller and said front idler roller spaced a selected distance above said drive roller;
- said housing including a front feed chute and rear discharge chute on flow communication with said roller assembly;
- a detachable paper feed dampener projecting forward and tilting downward at a selected angle from said feed housing below said feed chute, said detachable paper feed dampener having an inwardly curving end portion for supporting and guiding a feed paper sheet into said feed chute, said feed dampener imparting frictional drag to said feed paper sheet;
- and a paper tray for supporting a roll of paper spaced apart from and in alignment with said detachable paper feed dampener;
- pulling said paper sheet from said paper roll forward slightly to redistribute its weight on a top surface of said paper idler cylinder minimizing contact of said paper roll with said panel;
- allowing said paper roll to rock back against said panel upon ceasing pulling of paper sheet from said paper roll imparting drag on said paper roll preventing freewheeling and bird nesting of said paper roll by braking said paper feed roll.
