Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
393 words
An apparatus for splicing a leading end of a fully wound web roll, which has not yet been unwound, with a web running from an exhausting web roll which is being continuously unwound, comprising: a mill roll stand which contains opposing side frames, a rotary frame rotatably mounted between said opposing side frames, said rotary frame being provided with means for rotatably mounting said fully-wound web roll and said exhausting web roll in a mutually opposing relationship, means for rotating the rotary frame to place the fully-wound web roll in the splicing position and the exhausting web roll in the unwinding position; web guiding means disposed on the rotary frame for guiding the web from the exhausting web roll placed in the unwinding position; means for rotating, up to the speed of the running web, the fully wound web roll which is placed in the splicing position prior to the splicing operation; a web pushing roll provided near the fully-wound web roll placed in the splicing position, the web pushing roll being rotatably supported by a pair of arms pivotally suspended from a stationary member disposed above the mill roll stand, and being adapted to move toward and away from the fully-wound web roll while guiding the web from the exhausting web roll on a portion of the web pushing roll surface facing toward the fully-wound web roll; an intermediate roll disposed between the fully-wound web roll placed in the splicing position and the web being guided on the surface of the web pushing roll, said intermediate roll being rotatably supported by a pair of arms which are pivotally suspended from said stationary frame so as not to interfere with the movement of said pair of arms supporting the web pushing roll, said pair of arms supporting said intermediate roll being adapted to be shortened and lengthened so as to place the intermediate roll into and out of the path of the motion of the web pushing roll; means for moving the arms supporting the web pushing roll to push the running web by said web pushing roll toward the fully-wound web roll placed in the splicing position or to push the intermediate roll toward the fully-wound web roll with the running web interposed between the web pushing roll and the intermediate roll placed in the path of the web pushing roll; and
