Apparatus for applying a correction sticker to a document

Claim 1

An apparatus for applying a correction sticker to cover a field on a document comprising: a frame; an application station located on said frame; locating means for locating a document so that a field to be covered on the document is positioned in operative relationship with said application station; supply means for supplying a plurality of correction stickers to said application station; said supply means including a carrier having a said plurality of correction stickers detachably secured thereto in spaced relationship on said carrier; said plurality of correction stickers having pressure sensitive adhesive thereon; separating means located at said application station for separating a correction sticker from said carrier as said carrier is moved relative to said application station; moving means for moving said carrier so as to position a leading edge of a correction sticker in an application position relative to said field to be covered; said moving means including a lever which is pivotally mounted in said frame for movement between first and second positions in said frame; said lever when moved away from said application station incrementally towards said first position being effective to incrementally feed a correction sticker towards said application position; said lever having a roller directly thereon to press said leading edge of a correction sticker into adherence with the associated document at the application station as said lever is moved to said second position and to also press the remaining portion of said correction sticker over the field on said document as said lever is retained in the second position and the document is pulled out of the application station; said separating means including an ejector plate and a pressure plate which are positioned at said application station; and said moving means including a feed wheel to engage said carrier and also including coupling means for coupling said feed wheel to said operating lever to enable said feed wheel to move said carrier towards said application station; said carrier with said plurality of correction stickers thereon being threaded between said ejector plate and said pressure plate so as to enable the leading edge of a correction sticker to be moved towards said application position as said feed wheel moves said carrier, said ejector plate having a reverse bend therein to enable the correction sticker whose leading edge is being moved towards application position to be partially separated from said carrier, and said pressure plate being effective to maintain the correction sticker in a substantially parallel position relative to a document positioned in operative relationship with said application station until the leading edge of the correction sticker is moved into adherence with said document at said application station by said roller; and said coupling means also including a one way clutch coupled between said operating lever and said feed wheel to enable said feed wheel to move said carrier only when said operating lever is moved from said second position towards said first position and to hold said carrier stationary as said operating lever is moved from said first position to said second position.

Claim 2

An apparatus for applying a correction sticker to cover a field on a document comprising: a frame; an application station located on said frame; locating means for locating a document so that a field to be covered on the document is positioned in operative relationship with said application station; supply means for supplying a plurality of correction stickers to said application station; said supply means including a carrier having a said plurality of correction stickers detachably secured thereto in spaced relationship on said carrier; said plurality of correction stickers having pressure sensitive adhesive thereon; separating means located at said application station for separating a correction sticker from said carrier as said carrier is moved relative to said application station; moving means for moving said carrier so as to position a leading edge of a correction sticker in an application position relative to said field to be covered; said moving means including a lever which is pivotally mounted in said frame for movement between first and second positions in said frame; said lever when moved away from said application station incrementally towards said first position being effective to incrementally feed a correction sticker towards said application position; said lever having a roller directly thereon to press said leading edge of a correction sticker into adherence with the associated document at the application station as said lever is moved to said second position and to also press the remaining portion of said correction sticker over the field on said document as said lever is retained in the second position and the document is pulled out of the application station; said separating means including an ejector plate and a pressure plate which are positioned at said application station; and said moving means including a feed wheel to engage said carrier and also including coupling means for coupling said feed wheel to said operating lever to enable said feed wheel to move said carrier towards said application station; said carrier with said plurality of correction stickers thereon being threaded between said ejector plate and said pressure plate so as to enable the leading edge of a correction sticker to be moved towards said application position as said feed wheel moves said carrier, said ejector plate having a reverse bend therein to enable the correction sticker whose leading edge is being moved towards application position to be partially separated from said carrier, and said pressure plate being effective to maintain the correction sticker in a substantially parallel position relative to a document positioned in operative relationship with said application station until the leading edge of the correction sticker is moved into adherence with said document at said application station by said roller; and said coupling means also including a one way clutch coupled between said operating lever and said feed wheel to enable said feed wheel to move said carrier only when said operating lever is moved from said second position towards said first position and to hold said carrier stationary as said operating lever is moved from said first position to said second position.
