Abstract

The roll winding machine for alternately forming a web roll on two driven arbors. It has a splicing device for receiving a continuously running web from a web accumulator. The splicing device has a splicing carriage for receiving and holding the distal end portion of a leader web and including cutting means for severing the running web so that a severed end portion is provided on the wound web roll and on the continuously running web. A web clamping means is provided to grip and prevent movement of the running web and to release both the severed end portion of the web of the wound roll and the running web. The splicing carriage is operative to cut the running web and affix the severed end portion of the running web to the distal end portion of the leader web so that the running web is wound on the other driven arbor upon movement of the clamping means to release the running web and leader web.

A roll winding machine for receiving a continuously running web from a source thereof and winding the web on a core to from a web roll, the machine comprising

(a) support means;
(b) a web accumulator supported means for receiving the continuously running web to be wound from the source thereof;
(c) a splicing device supported by the support means for receiving the web to be wound from the web accumulator;
(d) a first driven arbor supported for rotation by the support means and carrying the core upon which the web running from the splicing device is to be wound to form a first web roll;
(e) a second driven arbor supported for rotation by the support means adjacent the first arbor and carrying a second core having affixed thereto one end of a leader web and upon which a second web roll is to be wound;
(f) motor means for alternately rotatively driving said first and second arbors;
(g) said splicing device having
(g-1) a splicing carriage means for receiving and holding the distal end portion of said leader web and including cutting means for severing the running web to be wound so that a severed end portion is provided on the first web roll, and on the running web to be wound into said second web roll;
(g-2) web clamping means operative in one position to grip and prevent movement of the running web and, in another position, to release both the severed end portion of the first web roll and the running web to be wound into said second web roll;
(g-3) said splicing carriage means including the cutting means being operative to cut the running web to be wound after it is wound to the extent predetermined on said first web roll and affix the severed end portion of the running web to be wound into said second web roll to the distal end portion of the leader web so that the running web is capable of being wound on the second core supported on the second arbor upon movement of the clamping means to a position to release the running web and the leader connected to said second core.
