Double envelope for standard production printing

Abstract

A method and apparatus includes/uses a media supply that maintains the media sheets and a printing engine that places markings on the sheets. The media sheets have multiple opposing partially formed envelopes. The markings placed have opposite orientations on the opposing envelopes. The apparatus also optionally includes a separator that separates the opposing partially formed envelopes after the printing engine places the marking, to leave partially formed individual envelopes. A folder device optionally folds the partially formed individual envelopes to produce completed individual envelopes.

1 . An apparatus comprising:
 a media supply maintaining media sheets, said media sheets comprising multiple opposing partially formed envelopes;   a printing engine placing markings on said sheets of said opposing partially formed envelopes, said markings having opposite orientations on opposing envelopes of said opposing partially formed envelopes;   a separator that separates said opposing partially formed envelopes after said printing engine places said marking to leave partially formed individual envelopes; and   a folder that folds said partially formed individual envelopes to produce completed individual envelopes.   
     
     
         2 . The apparatus according to  claim 1 , said media sheets comprising a separating line between pairs of said opposing partially formed envelopes. 
     
     
         3 . The apparatus according to  claim 2 , said separator dividing said media sheets along said separating line. 
     
     
         4 . The apparatus according to  claim 2 , said folder folds a panel of said partially formed individual envelopes bordering said separating line toward a center of said partially formed individual envelopes. 
     
     
         5 . The apparatus according to  claim 1 , said opposite orientations comprise a first orientation and a second orientation upside down with respect to said first orientation. 
     
     
         6 . An apparatus comprising:
 a media supply maintaining media sheets, said media sheets comprising pairs of opposing partially formed envelopes;   a printing engine placing markings on said sheets of said opposing partially formed envelopes, said markings having opposite orientations on opposing envelopes of said opposing partially formed envelopes;   a separator that separates said opposing partially formed envelopes after said printing engine places said marking to leave partially formed individual envelopes; and   a folder that folds said partially formed individual envelopes to produce completed individual envelopes; and   a roller nip based sheet feeding system providing a sheet path between said media supply, said printing engine, said separator, and said folder, said sheet feeding system having nip spacing larger than a size of said individual envelopes.   
     
     
         7 . The apparatus according to  claim 6 , said media sheets comprising a separating line between pairs of said opposing partially formed envelopes. 
     
     
         8 . The apparatus according to  claim 7 , said separator dividing said media sheets along said separating line. 
     
     
         9 . The apparatus according to  claim 7 , said folder folds a panel of said partially formed individual envelopes bordering said separating line toward a center of said partially formed individual envelopes. 
     
     
         10 . The apparatus according to  claim 6 , said printing engine comprising one of a electrostatographic and xerographic printing device. 
     
     
         11 . A method comprising:
 supplying media sheets comprising multiple opposing partially formed envelopes;   placing markings on said sheets of said opposing partially formed envelopes, said markings having opposite orientations on opposing envelopes of said opposing partially formed envelopes;   separating said opposing partially formed envelopes after said printing engine places said marking to leave partially formed individual envelopes; and   folding said partially formed individual envelopes to produce completed individual envelopes.   
     
     
         12 . The method according to  claim 11 , said media sheets comprising a separating line between pairs of said opposing partially formed envelopes. 
     
     
         13 . The method according to  claim 12 , said separating comprising dividing said media sheets along said separating line. 
     
     
         14 . The method according to  claim 12 , said folding comprising folding a panel of said partially formed individual envelopes bordering said separating line toward a center of said partially formed individual envelopes. 
     
     
         15 . The method according to  claim 11 , said opposite orientations comprise a first orientation and a second orientation upside down with respect to said first orientation. 
     
     
         16 . A method comprising:
 supplying media sheets comprising multiple opposing partially formed envelopes using a roller nip based sheet feeding system;   placing markings on said sheets of said opposing partially formed envelopes, said markings having opposite orientations on opposing envelopes of said opposing partially formed envelopes;   separating said opposing partially formed envelopes after said printing engine places said marking to leave partially formed individual envelopes; and   folding said partially formed individual envelopes to produce completed individual envelopes   said sheet feeding system having nip spacing larger than a size of said individual envelopes.   
     
     
         17 . The method according to  claim 16 , said media sheets comprising a separating line between pairs of said opposing partially formed envelopes. 
     
     
         18 . The method according to  claim 17 , said separating comprising dividing said media sheets along said separating line. 
     
     
         19 . The method according to  claim 17 , said folding comprising folding a panel of said partially formed individual envelopes bordering said separating line toward a center of said partially formed individual envelopes. 
     
     
         20 . The method according to  claim 16 , said opposite orientations comprise a first orientation and a second orientation upside down with respect to said first orientation.
