A label pressing device adapted for use with a labeling machine, the labeling machine including
- a conveying device including opposite upper and lower conveyer belts that define a container positioning space therebetween for receiving a container such that upper and lower ends of the container are contacted by the upper and lower conveyer belts, respectively, and that convey the container in a conveying direction, and
- a label applying device for attaching a label on the container on the conveying device, the label having opposite first and second lateral label ends and a middle label portion between the first and second lateral label ends, the label applying device attaching the middle label portion on an initial label attaching portion of the container on the conveying device,
- said label pressing device comprising:
- a first press unit adapted to press a first segment of the label between the middle label portion and the first lateral label end against the container while the container is being conveyed by the conveying device in the conveying direction;
- wherein said first press unit includes:
- a first swingable arm adapted to be disposed so as to extend swingably from one of two opposite lateral sides of the conveying device into the container positioning space;
- a first pressing roller unit adapted to be disposed in the container positioning space of the conveying device, and connected rotatably to said first swingable arm;
- and a first driver for driving said first swingable arm to swing in a first angular direction while said first pressing roller unit presses firmly the first segment of the label from the middle label portion to the first lateral label end against the container being conveyed by the conveying device;
- and
- a second press unit adapted to press a second segment of the label between the middle label portion and the second lateral label end against the container while the container is being conveyed by the conveying device in the conveying direction;
- wherein said second press unit includes:
- a second swingable arm adapted to be disposed so as to extend swingably from the other of said two opposite lateral sides of said conveying device into said container positioning space;
- a second pressing roller unit adapted to be disposed in the container positioning space of the conveying device, and connected rotatably to said second swingable arm;
- and a second driver for driving said second swingable arm to swing in a second angular direction opposite to the first angular direction while said second pressing roller unit presses firmly the second segment of the label from the middle label portion to the second lateral label end against the container being conveyed by the conveying device.
