Abstract:
A method of advancing packaging blanks disposed standing upright in a magazine, one after the other, in a file or queue resting against the bottom of the magazine and disposed to be driven forwards through the magazine towards a stop at an outlet end for individual discharge comprises the file or queue of blanks being divided into two pressure zones, a first and forward pressure zone extending from the zone limit between the pressure zones up to the stop and displaying a first mutual pressure between neighbouring blanks, as well as a rear second pressure zone displaying a second mutual pressure between neighbouring blanks. The first mutual pressure is higher than the second mutual pressure. Another aspect of the disclosure pertains to an apparatus for carrying out advancement of the packaging blanks.
Abstract:
The disclosure relates to an apparatus (10) for pushing a number of packaging containers (12) which are supported in cassettes (18) in motion in a first direction in a packaging machine. The apparatus (10) comprises carriers (40) by means of which the packaging containers may be pushed from a first position to a second position in relation to said cassettes (18). According to the invention, the apparatus (10) comprises at least one belt (30, 32) which, in a first portion of the apparatus (10) moves in a second direction and in the second portion of the apparatus (10) moves in a third direction, and, between the first and the second portions, there is disposed a bending roller (24), and the second and third directions each make an angle (α) with the first direction, and finally the carrier (40) is connected to a shaft (38) which is secured to the belt (30, 32) by means of a clamping device.
Abstract:
An apparatus for sealing an open end of a package comprises a first longitudinally extending sealing jaw, bearing mounted on a first eccentric shaft rotatable around a first rotational axis, and a second longitudinally extending sealing jaw, bearing mounted on a second eccentric shaft rotatable around a second rotational axis, the second sealing jaw being parallel with the first sealing jaw. At least one motor drives rotation around the first and second rotational axis in opposite directions, wherein the first and the second sealing jaws oppose each other, and are allowed to oscillate between sealing and open positions by moving towards and away from each other. A first and second transversally extending guiding bar cooperate with the first and second eccentric shaft via guiding pins running in guiding grooves, such that transverse play between the first and the second eccentric shaft and the first and second sealing jaw is allowed.
Abstract:
The disclosure relates to an apparatus (10) comprising a turning mechanism which is adapted to change the orientation of a number of packaging containers (12) in motion in a filling machine, from a first orientation (20) to a second orientation (22), comprising a conveyor (26) provided with at least one carrier (28) to which at least one carrier unit is connected. According to the invention, the carrier unit is rotary in relation to the carrier (28) about a geometric axis of rotation and is adapted to carry the packaging container (12) in such a manner that the point of gravity of the packaging container during the change in orientation is substantially located on the geometric axis of rotation, and the point of gravity of the packaging container thereby maintains substantially the same direction and speed from the first to the second orientation (20, 22).
Abstract:
A sealing jaw assembly for a sealing unit, and in particular an arrangement for suspending a sealing jaw in a socket is disclosed. The arrangement is based on a first and a second spring arrangement wherein the action of the first spring arrangement onto the sealing jaw may be activated and deactivated.

Abstract:
A sealing unit for sealing and forming a packaging container is disclosed. The sealing unit operates on a principle that the motion of a pair of opposing sealing jaws is controlled by a cam-cam follower interaction combined with the action of a servomotor driving a cam wheel.
