## Abstract

A bag making and packaging machine sandwiches a tubular film between a first horn and a first anvil and ultrasonically transversely seals it. The bag making and packaging machine includes: a knife disposed in an anvil-side knife movement space formed in the first anvil; a knife-driving part, and guides provided to each of two ends of the first anvil, on which guide spaces, by which movement of the knife is guided when the knife is driven by the air cylinder, are formed. The width of the guide spaces with respect to a direction orthogonal to both a length direction and a movement direction of the knife is less than the width of the anvil-side knife movement space with respect to the same direction.

## Claims

### Claim 1

A bag making and packaging machine, comprising
a transverse sealing mechanism having a horn and an anvil that are configured to sandwich a tube-shaped film transported in a first direction between the horn and the anvil for ultrasonic sealing, and configured to transversely seal along a direction intersecting the first direction, the anvil being formed with a knife movement space;
a knife disposed in the knife movement space formed in the anvil;
a knife-driving part coupled to the transverse sealing mechanism and configured to drive the knife within the knife movement space such that the knife moves toward the horn when the film is transversely sealed so that a sealed bag is cut and separated from the tube-shaped film; and
a guide part provided at each end of the anvil, each of the guide parts defining a respective guide space therein such that movement of the knife is guided along the guide spaces when the knife is driven by the knife-driving part,
wherein
each of the guide spaces has a first width measured with respect to a second direction, which is orthogonal to a movement direction of the knife driven by the knife-driving part and orthogonal to a length direction of the knife, and the knife movement space defines a second width measured with respect to the second direction, the first width being less than the second width.

### Claim 2 (depends on 1)

The bag making and packaging machine according to claim 1, wherein
the guide part is a non-metal member that is separate from the anvil.

### Claim 3 (depends on 2)

The bag making and packaging machine according to claim 2, wherein
the guide part is secured to the anvil by a fastening member after the attaching position of the guide part to the anvil such that positioning of the guide part is adjustable relative to the anvil.

### Claim 4 (depends on 1)

The bag making and packaging machine according to claim 1, wherein
the horn and the anvil are respectively configured to be driven to revolve so that the tube-shaped film transported in the first direction is sandwiched and transversely sealed.

### Claim 5 (depends on 1)

The bag making and packaging machine according to claim 1, wherein
the guide spaces extend further toward the horn side beyond the knife movement space in a state in which the horn and the anvil sandwich the tube-shaped film therebetween.

### Claim 6 (depends on 1)

The bag making and packaging machine according to claim 1, wherein
a thickness of the knife is no more than 1.2 mm.
