Abstract

A label cutter comprises a movable cutting blade, a pre-tensioning device, and a trigger. The pre-tensioning device pre-tensions the cutting blade into an arrested position. Upon its release, the cutting blade moves from the arrested position to a cutting position for cutting a label strip. In the arrested position, the cutting blade is retracted behind a component of the cutter.

First claim

Having described the invention, and a preferred embodiment thereof, what is claimed as new, and secured by Letters Patent is:

1. An apparatus for use in a labeling machine, said apparatus comprising a first cutter, wherein said cutter comprises a movable cutting blade, a pre-tensioning device, and a trigger, wherein said pre-tensioning device pre-tensions said cutting blade into an arrested position, wherein said trigger releases said pre-tensioning device so that said cutting blade moves from said arrested position to a cutting position for cutting a label strip, wherein, when in said arrested position, said cutting blade is retracted behind a component of said cutter, and wherein said pre-tensioning device comprises a tensioning piece for manually pre-tensioning said pre-tensioning device.

2. The apparatus of claim 1 , wherein said pre-tensioning device comprises an elastic material.

3. The apparatus of claim 1 , wherein said pre-tensioning device comprises a spring.

4. The apparatus of claim 3 , wherein said pre-tensioning device comprises a releasable detent device for a pre-tensioned position of said spring.

5. The apparatus of claim 3 , wherein said spring comprises a first end that connects to said cutting blade.

6. The apparatus of claim 3 , wherein said spring comprises a first end that connects to a blade carrier.

7. The apparatus of claim 1 , wherein said component of said cutter behind which said cutting blade is retracted comprises an inner protective wall that faces a course of a label strip.

8. The apparatus of claim 7 , further comprising a slit formed in said inner protective wall, said slit being configured such that said cutting blade advances through said slit into a cutting position.

9. The apparatus of claim 1 , wherein said trigger comprises an electromagnetically operated trigger.

10. The apparatus of claim 1 , further comprising a second cutter identical to said first cutter, first and second guide rolls, and a splicing station, wherein said first guide roll and said first cutter define a first conveyor path for conveying a first label strip, wherein said second guide roll and said second cutter define a second conveyor path for conveying a second label strip, and wherein said splicing station is disposed to join said first and second label strips.

11. The apparatus of claim 10 , wherein said trigger is configured to be activated based on a signal indicative of an end of a label strip.

12. The apparatus of claim 10 , wherein said splicing station comprises first and second halves, each of which accommodates one of said two label strips, and wherein said first and second halves are mirror images of each other, wherein said first and second cutters are mirror images of each other, and wherein said first and second conveyor paths are mirror images of each other.

13. The apparatus of claim 10 , further comprising first and second swivel arms and first and second deflector rolls, wherein each deflector roll is on a corresponding swivel arm, and wherein each swivel arm is configured to transition between an open position and an operating position.

14. The apparatus of claim 13 , further comprising a tensioning lever that causes said swivel arm to transition from said operating position to said open position, and wherein said tensioning lever enables permits manual pre-tensioning of said pre-tensioning device.

15. The apparatus of claim 13 , further comprising an electrical contact element that interrupts a supply of power to said trigger when said swivel arm transitions from said operating position to said open position.

16. The apparatus of any one of claim 13 , wherein said first and second deflector rolls comprise components to which access is required for changing a label strip.
