Abstract

The invention relates to stacks of panels (1), in particular, laminated panels, packaged for transport or storage. Said stack comprises several coated panels, for example, laminated panels, panels made from plywood, fibreboard or wood panels. The stack further comprises a packaging, with at least one strap (3), going around the stack and/or at least one retainer element (2), on the front side of the stack for fixing the panels. For example, the strap or the retainer element is provided in addition to further packaging elements, such as shrink-wrap or cardboard completely or partly enclosing the panels. The retainer element can, for example, be fixed to the stack and enclose the front face of the stack. By means of both measures, either individually or in combination, the withdrawal and removal of single panels from the stack is hindered or prevented. For example the strap can run perpendicular to the longitudinal direction of the panels. The strap can also be of elastic embodiment andapplied such as to hold the individual panels tight. In a further embodiment, the strap lies so tightly on the stack that on withdrawing a panel, in particular, the outer panel, said strap is tipped in the longitudinal direction of the stack and thus tightens preventing a further withdrawal. By arrangement of the strap perpendicular to the longitudinal direction of the stack, the possibility of stacking several stacks on top of each other is not affected.

Description

Laminate packaging

Technical field

The present invention relates to folded group (stacks of panels) of panel, especially for the ply wood (laminate panels) of transportation and storage.

Background technology

Usually, ply wood is packed in the mode of the group of layering, for example, and 4 to 10 panels.Folded group (stack) is used astrafoil (foil) shrink wrapping (shrink-wrapped) and/or usually with special shape or FOLD AND PACK carton package.These paper tinsels for example are based on polyethylene, the contraction paper tinsel of polyvinylchloride or polyethylene terephthalate.Packing or paper tinsel are limited to be made as certain volume and quality according to the packing decree.This packing or paper tinsel have such shortcoming, and promptly in order to remove independent panel, packing or paper tinsel can be torn at an easy rate by hand or sharp objects.

This situation may occur in the DIY shop.For instance, be placed on cash shopping in the DIY store display cabinet and transport commodity (cash and carry goods) voluntarily and opened by the customer, to pull out independent panel partially or completely, for example in order to estimate surface design better through regular meeting.In addition, under the more sharp-pointed situation in the edge of the vertical transport of folded group and panel, paper tinsel can be in some positions can be all to excessive extruding and can break.These panels, particularly outermost panel in the packing can not put back in the packing difficult afterwards or fully with having difficulty.Because the customer holds the attitude of suspection usually to the retail packaging of opening, i.e. the state of commodity and quality, therefore the product of the lamination of opening generally is difficult to sell.

Summary of the invention

Consider above-mentioned shortcoming, therefore, the purpose of this invention is to provide the folded group of a kind of plate, to improve packing.

According to the present invention, folded group of a kind of a plurality of laminate panel, it has the packing of folded group and prevent the device that panel is removed from packing, wherein, the described device that prevents that panel from removing from packing has a hold assembly at least, it is installed with on a side of this folded group, and make by cardboard with folding line, and band shape or bar shaped strengthening part, this strengthening part is arranged at least in part between described packing and described folded group and along at least one folded edge of described hold assembly and arranges, this makes it possible to offset because the weakening strength of the folding described hold assembly that causes has been strengthened folded edge simultaneously.

Comprise a plurality of folded group of plates according to folded group of the present invention.For example, they are ply wood, veneer sheet, panel, board fiber board or plank.In addition, folded group has packing.In addition, provide the device that prevents to remove plate from packing.These devices for example comprise preventing from packing is produced the general protection that damages.For example damage to owing to the mechanical collision that acts on the packing produces.These mechanical pressures for example produce in the transportation of folded group or by using sharp objects that packing is intentionally clashed into.In another embodiment, prevent that the device that panel is removed from also limiting the degree of freedom of panel motion in folded group in addition, so, constituted the Additional Protection that prevents that independent panel from removing from packing than Traditional Packing.Its advantage is, pulls out or take out independent panel thereby the difficulty or be prevented from of becoming from folded group.
