Abstract
Official abstract text for this publication.
The invention relates to a cross seam joining device for a flexible packaging having at least one ultrasonic applicator ( 13 a - 13 c ), which is rotatably mounted on a shaft ( 13 d ) and can be rotated about an axis ( 13 e ) of the shaft ( 13 d ) arranged longitudinally to the cross seam ( 110, 111 ). The ultrasonic applicator ( 13 a - 13 c ) is designed to produce and bundle ultrasounds in a frequency range of 0.1 MHz-0.5 MHz, preferably from 0.5 MHz-2 MHz.
First claim
Opening claim text (preview).
What is claimed is: 1. A cross seam joining device for a flexible packaging, the device comprising at least one ultrasonic applicator ( 13 a - 13 c ), which is mounted on a shaft ( 13 d ) and is configured be rotated about an axis ( 13 e ) of the shaft ( 13 d ) arranged longitudinally to the cross seam ( 110 , 111 ), characterized in that the ultrasonic applicator ( 13 a - 13 c ) is configured to produce and bundle ultrasounds in a frequency range of 0.1 MHz to 5 MHz, wherein the ultrasonic applicator ( 13 a - 13 c ) comprises an ultrasonic transducer ( 37 ), a focusing assembly ( 38 ) and a sound conductor ( 39 ), wherein the ultrasonic transducer ( 37 ) is plate-shaped and the focusing assembly ( 38 ) is lenticular, and the device further includes a ceramic counter holder ( 14 ). 2. The device according to claim 1 , characterized in that the ultrasonic applicator is mounted adjacent to the ultrasonic transducer ( 13 a ) on a carrier ( 13 ) connected by means of the shaft ( 13 d ). 3. The device according to claim 1 , wherein the counter holder ( 14 ) is rotatably mounted about an axis ( 13 f ), which is disposed parallel to the axis ( 13 e ) of the shaft ( 13 d ), and is provided with at least one blade ( 43 ). 4. The device according to claim 3 , characterized in that the blade ( 43 ) is integrated on the counter holder ( 14 ). 5. The device according to claim 3 , characterized in that the blade ( 43 ) is disposed adjacent to the counter holder ( 14 ). 6. The device according to claim 1 , characterized in that respectively one ultrasonic applicator is disposed on both sides of the cross seam in order to form a head seam-cross seam ( 110 ) and a foot seam-cross seam ( 111 ). 7. The device according to claim 1 , characterized in that the ultrasonic applicator ( 13 a - 13 c ) is configured to produce and bundle ultrasounds in a frequency range from 0.5 MHz to 2 MHz.
