For example, the lower edges are close to each other. In the state where the pair of plate-shaped guides are inclined in the opposite directions, the linear guides extending in the width direction of the label forming base material M are arranged opposite to each other with the traveling line of the label forming base material M interposed therebetween. It is also possible to place the label forming base material M opposite to each other with the travel line of the label forming base material M sandwiched between them.

  Further, in the above-described embodiment, the skewer guide 62 facing the skewer guide 63 with the travel line of the label forming substrate M interposed therebetween is disposed, but the skewer guide 62 is omitted. Is also possible.

  In embodiment mentioned above, although the label supply apparatus 4 mounted in the label fitting system 1 for fitting the cylindrical label L to the trunk | drum of the bottle B was demonstrated, it is not limited to this, The present invention can be applied to various label processing systems in which a sheet-like label needs to be supplied to a predetermined position at a predetermined timing.

  INDUSTRIAL APPLICABILITY The present invention can be used when forming a label having a predetermined length while sequentially cutting a long label-forming substrate and sequentially supplying the label to a predetermined position.
