Abstract
The versatility of a slotter device, a sheet slicing method and a carton former is improved by providing first slotter heads and first lower blades, first slotter knives and second slotter knives mounted on the circumferences of the first slotter heads, second slotter heads and second lower blades, third slotter knives and fourth slotter knives mounted on the circumferences of the second slotter heads, third slotter heads and third lower blades, and fifth slotter knives and sixth slotter knives mounted on the circumferences of the third slotter heads, to process cuts of differing lengths.
Claims11
A slotter device comprising:
- a first upper slotter head and a first lower slotter head which are supported so as to be rotatable relative to each other and perform slicing of a sheet;
- a first slotter knife and a second slotter knife which are mounted on an outer peripheral portion of any one of the first upper slotter head and the first lower slotter head;
- a second upper slotter head and a second lower slotter head which are supported so as to be rotatable relative to each other and perform the slicing of the sheet;
- a third slotter knife and a fourth slotter knife which are mounted on an outer peripheral portion of any one of the second upper slotter head and the second lower slotter head;
- a third upper slotter head and a third lower slotter head which are supported so as to be rotatable relative to each other and perform the slicing of the sheet;
- and
- a fifth slotter knife and a sixth slotter knife which are mounted on an outer peripheral portion of any one of the third upper slotter head and the third lower slotter head.
A sheet slicing method of performing slicing of a corrugated fiberboard by a first slotter head, a second slotter head, and a third slotter head juxtaposed in a transport direction of the corrugated fiberboard in a state where several corrugated fiberboards are connected to each other in the transport direction, the method comprising:
- a step of forming a first opening groove on one end portion of the corrugated fiberboard in the transport direction by a first slotter knife mounted on the first slotter head;
- a step of forming a communication groove on an intermediate portion of the corrugated fiberboard in the transport direction by at least two slotter knives of a second slotter knife mounted on the first slotter head, a third slotter knife and a fourth slotter knife mounted on the second slotter head, and a fifth slotter knife mounted on the third slotter head;
- and
- a step of forming a second opening groove on the other end portion of the corrugated fiberboard in the transport direction by a sixth slotter knife mounted on the third slotter head.
