A Closing apparatus () for closing packaging elements, in particular cardboard boxes, comprises conveying device () for conveying the packaging elements, a folding device () for folding down at least one section of the packaging element concerned, a first closing device () for closing at least one section of the packaging element concerned, arranged on a first longitudinal side of the conveying device (), wherein the closing apparatus further comprises a second closing device () for closing at least a section of the packaging elements concerned that is mounted on a second longitudinal side of the conveying device () opposite the first longitudinal side of the conveying device ().

Closing apparatus

The invention discloses a case clamp () for clamping of carcass parts into furniture carcasses, such as tall cupboards, top or bottom cupboards, having a base frame (), at least one pair of compression beams () provided on the base frame (), whereby at least one compression beam is traversable along the base frame in relation to the other compression beam, and at least one feed device () for transporting in carcass parts to be clamped and/or for transporting out clamped carcasses. The case clamp according to the invention is characterized in that the case clamp () also has an ultrasonic welding device ().

Case clamp

A case clamp () for clamping carcass parts to furniture carcasses, such as tail cupboards, top or bottom cupboards, having a base frame (), a lower compression beam (') provided on the base frame (), at least two supports () disposed on the base frame (), of which at least one is traversable horizontally on the base frame (), at least two pairs of horizontal compression beams () disposed on the supports () so as to be horizontally traversable, and an upper compression beam () disposed on the supports () so as to be vertically traversable, wherein in each case the supports () are supported exclusively on the base frame () in the vertical direction at least and are free at the opposing end (&#x2032;).

The invention relates to a device for returning machined workpieces from the delivery side of a first machining unit to the feeding side of the first or of another machining unit. The inventive device comprises the following: a transfer device () for transferring the machined workpieces to the delivery side of the first machining unit; a lifting device for lifting the workpieces, which are delivered by the transfer unit, into a return position located above the transfer unit, and; a return device () for conveying the workpieces, which are delivered by the lifting device, back to the feeding side of the first or the other machining unit. The transfer device () comprises a transfer table with interspaced first supporting elements () for the workpieces. The lifting device comprises at least one lifting table () that, in turn, has interspaced second support elements (), which can be upwardly guid through between the first support elements () of the transfer table. The lifting device comprises at least one drive unit (), which moves the at least one lifting table () in a rotary motion from the transfer table upwards to the return position and back to the transfer table.

Device for returning workpieces

To simplify and speed up folding of plate-like elements () along a fold line (), more particularly in a continuous operation, a method and a an apparatus for folding plate-like elements () are proposed which eliminate the use of counter-impression elements in the region of the fold line (). The apparatus includes a second impression device () that folds a second section () of the plate-like element () about the fold line () by a first force component oriented perpendicular to the plane of the second section (). At the same time the second impression device () produces a second force component oriented in the plane of the second section () and acting in the direction of the fold line () to urge a first section () of the plate-like element () against a first impression device ().

Apparatus for folding cardboard articles

The present invention relates to a folding machine and a method of automatically folding a folding box made of a pre-grooved carton blank. The folding machine according to the invention is provided with at least one alignment means (,) for aligning said carton blank into a predeternined position on a receiving plane, a pre-folding flap (,) assigned to one tab (,) of said carton blank at a time for lifting said tabs (,) out of the receiving plane, said pre-folding flaps (,) being movable on the receiving plane, at least one fixing means (,) for securing said carton blank, at least one erecting flap (,) assigned to one side wall (,) of said carton blank at a time, said erecting flap being movable on the receiving plane, and at least one connecting means assigned to one tab (,) at a time for connecting said tab (,) to the associated side walls.

Folding machine and process for automatic folding of a folding box

A feed and stacking device for slab-shaped workpieces has a rigid frame which is pivotally mounted on a base stand for movement between a horizontal position and a raised position. A support bar is movable along the length of the frame and carries a plurality of vacuum operated pick-up devices for transferring a workpiece from a stack to a processing device or vice versa.
