Abstract
A waste removing method capable of easily carrying out a waste removing operation to peel a label sheet waste off a base sheet. A label sheet 4b of label paper 4 being conveyed along a path of label paper conveyance 1 is formed with a cut line 4h for peeling-off; an upstream side portion 4i of label sheet bordered and starting with the cut line 4h is peeled off a base sheet 4a, and the portion of label sheet 4b peeled off is carried to and wound onto a waste take-up member 20 whereby winding the peeled-off portion of label sheet 4b onto the waste take-up member 20 causes a label sheet waste 4g of succeeding label paper 4 to be peeled off the base sheet 4a and taken up onto the waste take-up member. The waste removing operation can be carried out automatically.
Claims5
A label paper waste removing method, characterized in that it comprises steps of:
- forming a label sheet of label paper with a cut line for peeling off which is continuous widthwise thereof;
- peeling off a base sheet an upstream side portion of sheet of label paper bordered and starting with said cut line, the label paper being conveyed along a path of label paper conveyance;
- carrying said portion of label sheet peeled off to a waste take-up means;
- and
- winding onto said waste take-up means, said portion of label sheet carried to the waste take-up means,
- whereby winding the portion of label sheet onto the waste take-up means causes a label sheet waste of succeeding label paper to be peeled off the base sheet and taken up onto the waste take-up means,
- wherein said upstream side portion of label sheet bordered and starting with said cut line is peeled off said base sheet while label paper is conveyed as it is being bent at a sharp angle in a region of the path of label paper conveyance;
- and
- after said portion of label sheet peeled off is wound onto said waste take-up means, label paper is conveyed linearly over said region of the path of conveyance and the label sheet waste is then peeled off by a waste peeling-off member.
A label paper waste removing apparatus comprising:
- a peel-off initiating mechanism operative to peel off a base sheet an upstream side portion of the label sheet bordered and starting with a cut line for peeling-off;
- and
- a label sheet conveyer means and a waste take-up means, said label sheet conveyer means being operative to carry to said waste take-up means, said portion of label sheet peeled by said peel-off initiating mechanism, to wind it onto said waste take-up means,
- whereby winding the portion of label sheet peeled off onto the waste take-up means causes a label sheet waste of succeeding label paper to be peeled off the base sheet and taken up onto the waste take-up means,
- wherein said peel-off initiating mechanism includes a peeling-off initiating member and a guide roll for peeling-off initiation, said guide roll being movable between a peeling-off position and a retraction position which are lower and upper than said path of label paper conveyance, respectively, such that the guide roller for peeling-off initiation when in said peeling-off position and said peeling-off initiating member allow the label paper to be conveyed while it is being bent at a sharp angle, thereby peeling off said upstream side portion of label sheet bordered and starting with said cut line, and
- said label sheet conveyer means includes a vacuum conveyer disposed above said peeling-off initiating member for carrying said peeled-off portion of label sheet while it is attracted to the conveyer by vacuum to said waste take-up means, said vacuum conveyer being movable between its carrying position and retraction position at which it is in contact with and remote from said waste take-up means, respectively.
