Benefits of technology

The patent describes a device for handling thin, flexible materials such as plastic or foil used in the manufacturing of peel-off lids. The device includes a hollow cylinder that moves freely within certain limits, allowing for a stable band loop even under high-speed conditions. A transversal bar is also included to limit the movement of the cylinder in both vertical and horizontal directions, and a straight delivery system is used to save on foil usage. The device also includes a mechanism to stabilize the band loop, allowing for consistent handling of the material even during fluctuations in step length or high delivering speeds.

Problems solved by technology

Preferably, a transversal bar lying horizontally and supported on both sides in the side walls runs through the hollow cylinder and limits the free mobility of the hollow cylinder.
This results in a particularly easy path limitation for the hollow cylinder.

Embodiment Construction

[0018]FIGS. 1 to 4 show an embodiment of an arrangement 1 according to the invention. It is provided and adapted to form a band loop 7 in a band 6. The band 6 is uncoiled from a band delivery spool 2 in an actuated manner and thereafter gets into the arrangement 1. Thereafter, the band is transported by a drawing-in device 4 which belongs to a device inside which the band is used or processed respectively. An example of such a device is explained in the following. The shown band transport reveals the band transport direction D. The uncoiling from the band delivery spool is normally done with constant speed or it may be adjusted to fast speed changes of the drawing-in device 4 via the actuator 19 only comparatively slowly. Particularly, the drawing-in device 4 can cause a stepwise drawing-in of the band with changing drawing-in lengths. Thereby, the arrangement 1 has the purpose to compensate for the drawing-in fluctuations with respect to speed and / or drawing-in step lengths by mean...

Abstract

When handling a foil band (6) which is to be uncoiled from a delivery spool (2) and is drawn in gradually by a drawing-in device (4), a foil band loop (7) is produced. In order that this can take place without any errors with high production cadences, provision is made of an arrangement (1) in which a hollow cylinder (10) rests loosely on the band with a limited freedom of movement so as to form the band loop. Such an arrangement is preferably provided for the production of peel-off lids, in which a foil band is uncoiled from a band delivery spool and fed to a stamping and sealing station.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the priority of Swiss patent application 0531 / 10, filed Apr. 13, 2010 and PCT Application No. PCT / CH2011 / 000071, filed on Apr. 4, 2011, the disclosures of which are incorporated herein by reference in their entirety.FIELD OF THE INVENTION[0002]The invention is related to an arrangement for forming a band loop between a delivery spool which is actuated in an uncoiling manner and a band drawing-in device. Particularly, the arrangement is used for a method to produce peel-off lids, comprising the forming of a plurality of parallel rows of lid rings made of metal, wherein a stepwise transport of the lid parts to a plurality of processing stations and a stepwise delivery of a foil band from a delivery spool to the lid rings and the stamping out of foil sections as well as the appliance and heat sealing of the foil sections onto the lid rings in a stamping and sealing processing station are carried out, wherein a foil ba...
