Abstract

Abstract An automatic paper feed device provided in a turnbar unit of a rotary press includes a slitter (1) for slitting a web of paper (2) in half. A paper feed rope (8) having a leader (7) connected thereto is located near the slitter. When the leading end of the web has passed through the slitter, the paper feed rope begins to move so that the leader will be moved in juxtaposition with the leading end of one of the two slitted webs. When the leading end of one of the webs reaches a predetermined position, a tape applicator (31) will be activated to apply tapes both to the leader and the leading end of one of the webs so as to straddle them. The web thus connected to the paper feed rope through the leader is guided by the rope through a predetermined paper feed path.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 158 words
An automatic paper feed device for a turnbar unit of a rotary press, comprising a slitter for slitting a web of paper being fed into two webs; a linear paper feed means having a leader connected thereto; said linear paper feed means being adapted to start moving substantially in the same direction as the feed direction of said web of paper when the leading end of said web has passed said slitter, so that said leader will be moved in juxtaposition with the leading end of one of said two slitted webs; a sensor for detecting the position of said leading end of said one of the webs and generating a signal; and laminating means adapted to be activated by the signal from said sensor to laminate said leader to said leading end of said one of the webs; whereby guiding said one of the webs through a predetermined paper feed path with said linear paper feed means.
Claim 2
Dependent Claim 158 words
