Abstract
A reel change apparatus for supplying a webbing material to a downstream machine has two sliding platens that are substantially linearly slidable between a respective standby position and a respective splicing position. Two reel holding members each hold a reeled web in a respective material supply position and a respective wait position. The two sliding platens have clamps for retaining a leading end of a new web. A pivotable platen has a clamp for retaining the trailing end of a running web. Adhesive provided on the leading end is exposed and supported on the sliding platens. The leading end of the new web may be retained on one sliding platen in the respective standby position while a running web passes over the other sliding platen.
Claims25
A reel change apparatus for supplying a webbing material to a downstream machine comprising:
- two reel holding means each arranged to hold a reeled web/webbing material, one in a material supply position and the other in a wait position, a first set of rollers arranged to guide webbing material from the reel in the material supply position over a first platen and towards the downstream machine, a second set of rollers arranged to guide wedding material from the reel in the wait position to a second platen;
- and
- a splicing means from which a running web can pass, in operation, to a downstream machine, the splicing means comprising a pivotable third platen and a retaining means for retaining or clamping a trailing end of a running web onto the pivotable platen;
- wherein the first and second platens are sliding platens positioned upstream of the splicing means, each including retaining means for retaining or clamping onto the respective sliding platen a leading end of a new web from a respective reel, such that an adhesive provided on the leading end is exposed and is supported by the respective sliding platen, and each of the sliding platens being substantially linearly slidable between a respective standby position and a respective splicing position;
- and
- wherein the leading end of a new web can be retained or clamped onto one sliding platen in the respective standby position while a running web passes over the other sliding platen to the downstream machine, and when the trailing end of the running web is retained or clamped onto the pivotable platen, the one sliding platen is slidable to the respective splicing position and the pivotable platen is pivotable to bring the trailing end of the running web into contact with the leading end of the new web to form a splice by sandwiching the adhesive therebetween, and subsequently to release the splice.
A splicing apparatus comprising;
- two spools, each for carrying a respective reeled web/webbing material;
- two sliding platens, each for receiving and supporting a web from one or other of said spools, and each comprising a clamp for clamping said web thereto;
- and,
- a splicing means comprising a pivotable third platen and a clamp for clamping a web thereto;
- each of said sliding platens being substantially linearly slidable between a respective standby position spaced from said splicing means and a respective splicing position in which said sliding platens are interoperable with said splicing means so that, in operation, while a running web is passing from one of said spools over one of said sliding platens and through said splicing means, a leading end of said web from said other spool can be clamped to said other sliding platen in the respective standby position, and when said running web ends, a trailing end of said running web can be clamped to said pivotable platen, said other sliding platen can be moved to the respective splicing position and said splicing means operated to form a splice between said trailing end and said leading end.
A reel-change apparatus comprising;
- two reel-holding means each arranged to hold a reeled web/webbing material;
- two sliding platens, each including a means for retaining or clamping a leading end of a new web thereon;
- and
- a splicing means mounted downstream of said sliding platens and from which a running web can pass, in operation, to a downstream machine, said splicing means comprising a pivotable third platen and a means for retaining or clamping a trailing edge of a running web onto said pivotable platen;
- in which each of said sliding platens is substantially linearly slidable into a respective splicing position and, when one of said sliding platens retaining said leading end is positioned in the respective splicing position, said pivotable platen is pivotable to bring said trailing end into contact with said leading end and to form a splice therebetween, and subsequently to release said splice.
