Abstract
A web threading and splicing system that provides easy access to the threading rolls by an operator. The new web supply roll for replacement of the expired web can be threaded at a standstill position adjacent the operator. This affords ease of access, which furnishes a great ergonomic and safety advantage, wherein the operator does not have to reach into moving web components in order to accomplish the splice.
Claims19
A web splicing system having operator movable threading assemblies, comprising:
- a first work station supporting a first web supply roll and a first operator movable threading assembly, and a second work station supporting a second web supply roll and a second operator movable threading assembly, said first and second operator movable threading assemblies each being manually movable between a web splicing/feeding position, where they are adjacent each other, and a web threading position at an extended location accessible to an operator, each movable threading assembly having a threading roll and web securing means for securing said web with respect to said threading roll and its respective first and second supply roll, said two threading rolls being pressed against each other during the splicing operation, and means carried upon said first and second work stations for splicing first and second webs of said respective first and second web supply rolls when both said movable assemblies are in the splicing/feeding positions.
A web splicing system having operator movable threading assemblies, comprising:
- means defining a web feed path;
- a first work station disposed along said web feed path, said first work station supporting a first web supply roll and a first operator movable threading assembly;
- a second work station disposed along said web feed path, said second work station supporting a second web supply roll and a second operator movable threading assembly, said first and second operator movable threading assemblies each being manually movable between a web splicing/feeding position, where they are adjacent each other, and a web threading position at an extended location accessible to an operator, each operator movable threading assembly having a web threading roll;
- splicing means carried upon said first and second work stations for splicing first and second webs of said respective first and second web supply rolls when both said operator movable threading assemblies are in their respective splicing and feeding positions;
- and
- web severing means proximate said web feed path for cutting a portion of said web after said splicing is performed.
A method of splicing an expiring web to a replacement web using manually positioned splicing units, comprising the steps of:
- a) moving a web threading roll from a web splicing position to an operator threading position;
- b) threading said web threading roll with a replacement web;
- c) moving said threading roll to said web splicing position;
- and
- d) splicing said replacement web to the expiring web on the fly using a manually positioned splicing unit.
