DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a method and a device for placing edge protecting means at pressure-sensitive edges on objects, preferably in connection with packaging said objects by means of band strapping.
When packaging objects by means of band strapping it is common practice, in order to preserve the edges of objects, to insert edge protecting means underneath the bands. This technique is employed within a plurality of various fields, for example in the wood industry for lumber packaging. In the past, ready-made edge protecting means were applied under the bands prior to tightening. When tightening, however, the bands will move irregularly making it diffucult to retain the edge protecting means in their proper position underneath the bands. As a consequence, the edge protecting means have often been misplaced, and therefore do more harm than good.
SUMMARY OF THE INVENTION
The object of the invention is to eliminate the above-mentioned disadvantages and to achieve a method and a device for the application of edge protecting means, enabling in a simple manner the edge protecting means to be correctly positioned without the risk of being displaced when tightening the bands during packaging. In accordance with the invention, this is accomplished with a method and a device having the characterizing features set forth in the attached claims.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will be described in more detail below while referring to the accompanying drawings, of which:
FIG. 1 is a somewhat schematic lateral view of a device according to one embodiment of the invention;
FIG. 2 is a frontal view of the device according to FIG. 1 with guide means for the device being indicated by dash-dotted lines;
FIG. 3 is a partially cut-away lateral view of the components included in the device shown in FIGS. 1 and 2 and intended to fulfill the desired function;
FIGS. 4 and 5 are lateral views corresponding to FIG. 3 but showing the components in alternative positions during a working cycle.
DETAILED DESCRIPTION OF THE INVENTION
The drawings illustrate a device 1 for placing edge protecting means at pressure-sensitive edges on objects, said device being contained in a housing 2 provided with an openable lid 3. There is further a removable cover 4 by means of which different parts in the device 1 can be reached for maintenance and repair. As is indicated by dash-dotted lines in FIG. 2, guide means 5 are mounted on the housing 2, said guide means 5 serving to facilitate for the device 1 to be positioned at the edge intended for the application of the edge protectng means. In order for the device 1 to be fixed in position on this edge, said device is secured to carrier means (not shown) for adjustably supporting the device and for enabling it to be placed in any predetermined position on the edge in question. The parts of the device 1 accommodated inside the housing 2 are carried by a body 6 which is only partially illustrated in the drawings.
The edge protecting means 7, intended to be placed by means of the inventive method and device, consist in a known manner of angular strips to be inserted under the bundling bands used for holding together a package of objects having pressure sensitive edges such as a package of wood, for example. With the method and the device according to the invention, the edge protecting means 7 will be given their final shape only in connection with their placement at the point of application, and a large number of blanks for edge protecting means are accommodated in the housing 2 of the device 1 in the form of a continuous band wound to a magazine such as a reel, which can be introduced into the housing 2 via the lid 3. The band, which is denoted 7a in FIGS. 3-5, is pulled out of the reel, passed through a slot 8 in a front end wall 9 of the device, and fed out to form an edge protecting means 7. The slot 8 is angularly shaped with an obtuse angle, which means that the band 7a at its passage through the slot 8 is subjected to a bending moment around a lo
