DESCRIPTION:
BRIEF SUMMARY
The invention relates to a method of manufacturing sleeve- or bag-like containers, wherein two superimposed bands of material lying one above the other are cut transversely into separate container parts which are connected to each other at the cut edges as formed.
In a known method of this type which is used for manufacturing sleeve-like- containers for flower bunches known as flower sleeves, the bands of material are arranged with respect to each other in transverse direction such that one container part protrudes beyond the other container part on the opening side. The protruding portion or the extension of the one container part is thereafter perforated along a line thereby creating a tear line defining the opening edge of the respective container part. A plurality of containers is then connected at the extensions thereof. When the containers are to be provided around the bunches of cut flowers, a stack of containers is clamped at the extensions and the containers are teared off one-by-one along the tear line.
When it is desired to have containers of which the opening edges are machined, for instance cut as an ornamental edge, a stack of containers connected at the extensions is cut off below the tear line in a separate apparatus. Then there is provided a stack of loose containers difficult to handle when the containers are arranged around the bunches of cut flowers.
It is an object of the invention to provide a method of the type mentioned in the preamble, with which all kinds of sleeve- or bag-like containers having edges shaped in any form can be manufactured automatically.
For this purpose the method according to the invention is characterized in that the bands of material, prior to cutting them into separate containers, are separated on at least one longitudinal edge, whereafter at least one of these longitudinal edges of the bands of material is machined.
Due to these features the respective longitudinal edges of both bands of material may undergo different machining operations and it is for instance possible to manufacture in a simple way containers of which the opening edges of both container parts differ in shape or position due to the machining operation.
It is suitable for seperating the bands of material to guide them at least at the respective longitudinal edge thereof on either side of a flat seperating body.
As a result thereof there is effected a seperation of the bands of material at the respective longitudinal edge in a very simple way.
In an embodiment of the method wherein the bands of material are supplied simultaneously and stepwise, it is favourable according to the invention if the longitudinal edge of the bands of material are machined by die-cutting, preferably by means of heat.
The use of the heat is prefered in the case of materials that are difficult to cut, such as some types of plastic foils.
According to a further development of the method according the invention it is possible to machine the separated longitudinal edges of both bands of material into opening edges of the containers, wherein it is advantageously that the longitudinal edge of one band of material is cut off completely up to the opening edge of the respective container part, while the longitudinal edge of the other band of material remains connected to the opening edge of the other container part by a formed tear line.
Due to this measures it is for instance possible to manufacture containers that can be used as flower sleeves, wherein the opening edges of the container parts are defined by ornamental lines, while it is still permitted to provide one of the container parts with an extension connected by tear portion.
The invention also includes an apparatus for manufacturing sleeve- or bag-like containers using the method described hereinbefore, comprising means for supplying two superimposed bands of material, and cutting and connecting means extending across the bands of material for separating container parts from the bands of material and connecting them into a container.
