Abstract
Abstract A device for use in conjunction with a compartmented distribution line for flat articles, such as letters, which arrive in succession over a conveying path. The device comprises a succession of stacking compartments arranged one behind the other to which the flat articles are supplied by switches separately associated with the individual compartments. On the conveying path, closely before each individual stacking compartment, there is provided a rubber elastic roller-type attachment which faces the upper edge of each flat article against a guide sheet disposed opposite the attachment.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
116 words
In a compartmented distribution line for flat articles, such as letters, arriving in succession over a conveying path, a device comprising a succession of stacking compartments arranged one behind the other to which said flat articles are supplied by switches separately associated with the individual compartments, and wherein, on the conveying path, closely before each individual stacking compartment, there is provided a rubber elastic roller-type attachment which forces the upper edge of each flat article against a guide sheet disposed opposite said attachment, and wherein further on the conveying path, closely before each individual stacking compartment and below the roller-type attachment there is disposed a rimmed roller which imparts a stiffening curvature to said flat articles.
Claim 2
Dependent Claim
116 words
In a compartmented distribution line for flat articles, such as letters, arriving in succession over a conveying path, a device comprising a succession of stacking compartments arranged one behind the other to which said flat articles are supplied by switches separately associated with the individual compartments, and wherein, on the conveying path, closely before each individual stacking compartment, there is provided a rubber elastic roller-type attachment which forces the upper edge of each flat article against a guide sheet disposed opposite said attachment, and wherein further on the conveying path, closely before each individual stacking compartment and below the roller-type attachment there is disposed a rimmed roller which imparts a stiffening curvature to said flat articles.
Claim 3
Dependent Claim
55 words
A device according to claim 1, wherein, on the conveying path, immediately before each individual stacking compartment, there is disposed a stacking spindle comprised of a conical helical body, said stacking spindle transporting each incoming flat article to the stacking compartment in the direction of the ascent of the helix of said conical helical body.
Claim 4
Dependent Claim
45 words
A device according to claim 2, wherein the respective end of said stacking spindle at the side of the bottom of said conical helical body supports an associated stack of said flat articles, said flat articles being shaken by the discharge end of said helix.
Claim 5
Dependent Claim
43 words
A device according to claim 3, wherein each stacking spindle is positioned so that, during the transport of said flat articles through said stacking spindle, only the lower edge of each article is transported out of the insertion region at the same speed.
Claim 6
Dependent Claim
43 words
A device according to claim 2, wherein each stacking spindle is positioned so that, during the transport of said flat articles through said stacking spindle, only the lower edge of each article is transported out of the insertion region at the same speed.
Claim 7
Dependent Claim
55 words
A device according to claim 1, wherein, on the conveying path, immediately before each individual stacking compartment, there is disposed a stacking spindle comprised of a conical helical body, said stacking spindle transporting each incoming flat article to the stacking compartment in the direction of the ascent of the helix of said conical helical body.
Claim 8
Dependent Claim
45 words
A device according to claim 6, wherein the respective end of said stacking spindle at the side of the bottom of said conical helical body supports an associated stack of said flat articles, said flat articles being shaken by the discharge end of said helix.
Claim 9
Dependent Claim
43 words
A device according to claim 6, wherein each stacking spindle is positioned so that, during the transport of said flat articles through said stacking spindle, only the lower edge of each article is transported out of the insertion region at the same speed.
