Abstract
A sheet cutting apparatus and a sheet cutting method using the same are disclosed. In one aspect, the sheet cutting apparatus includes a holder for rotatably supporting a sheet roll, a lamination unit for pulling and unwinding a front end of the sheet unwound from the sheet roll, a table on which the sheet unwound by the lamination parts is attached, and a tension unit for giving tension to the sheet attached on the table. Since the sheet cutting apparatus may cut the sheet consistently and stably, product quality and production efficiency should increase.
Claims8
A sheet cutting apparatus comprising:
- a holder configured to rotatably support a sheet roll;
- a lamination unit configured to pull and unwind a front end of a sheet from the sheet roll;
- a table on which the sheet unwound by the lamination unit is attached;
- and
- a tensioner configured to provide tension to the sheet attached on the table
The apparatus of claim1, wherein the tension unit is installed between the holder and the table and wherein the tension unit further comprises a tension roller configured to provide backward tension to the sheet attached on the table
The apparatus of claim1, wherein the lamination unit further comprises:
- a pair of lamination rollers configured to grasp a front end of the sheet roll;
- and
- a guide unit configured to guide the pair of lamination rollers to travel on the table.
The apparatus of claim1, wherein the guide unit is configured to guide the lamination rollers along a circular path so that the lamination rollers go forward and then descend without contacting the table and come backward while contacting the table.
The apparatus of claim1, further comprising a cutter configured to cut a rear end of the sheet attached on the table.
A sheet cutting method comprising:
- pulling and unwinding a front end of a sheet from a sheet roll,
- attaching the unwound sheet on a table,
- giving tension to the sheet while the sheet is attached on the table, and
- cutting a rear end of the sheet attached on the table.
