Benefits of technology

[0013]That way, the adhesive can be applied only when the sealing band is about to be used so that adhesive is not applied on a large amount of sealing band material when the machine come to a stop in the event of a shutdown. It is therefore possible to use adhesive that does not weaken the resistance of the sealing band.

Problems solved by technology

Thus, a watery glue is used to prevent the glue from drying in the event of a machine shutdown which would mean the glue cannot stick the sealing band to the carton when the machine resumes operation.
This type of glue, however, tends to saturate the sealing band, making it more liable to tear when subjected to the pulling action of the machine, in turn making it necessary to scrap a certain number of cartons, with further machine shutdowns to remove the defective cartons, and with obvious disadvantages in terms of economic loss.

Embodiment Construction

[0022]A preferred embodiment 1 of the seal banding machine is illustrated in FIG. 2. The seal banding machine 1 is designed to apply a sealing band B to the lateral surface A11 of a container body A, illustrated in FIG. 1, with a circular profile, in particular constituting a carton for containing portions of a pasty food product, especially processed cheese.

[0023]The carton A provided with the sealing band B is, as illustrated in FIG. 1, composed of a first and a second opposed half-shells A1, A2, which face each other in such a way as to form a chamber for housing the product or processed cheese portions.

[0024]As may be well inferred from FIG. 1, the half-shells A1, A2 have respective flat faces A12, A13, from which corresponding perpendicular portions extend to engage with each other and together form the circular perimeter wall A11 of the carton which, along its centre line has a perimeter slot to be covered with a sealing band B, or strip, of paper or other material wound round...

Abstract

A seal banding machine (1) designed to apply a sealing band (B) to the lateral surface (A11) of a circular container body (A) includes: elements (11) which apply the sealing band (B) to the lateral surface (A11) of container body (A), which are rotatable about a respective axis and which have a surface (111) for retaining and supporting the sealing band (B); and elements (12) for rotating the container body (A) with the respective lateral surface (A11) engaging the peripheral surface (111) of the elements (11) which apply the sealing band (B). Elements (21) are provided for spreading an adhesive on the sealing band (B), which are located at the elements (11) for applying the sealing band (B).

Description

TECHNICAL FIELD[0001]This invention relates to a machine for applying a sealing band to the lateral surface of a container body.[0002]More specifically, the container body is a carton containing portions of a pasty food product, especially in the form of processed cheese.BACKGROUND ART[0003]Seal banding machines are known in the prior art which are designed to apply a sealing band to the circular lateral surface of a container body for holding portions of processed cheese.[0004]In particular, prior art seal banding machines operate with alternating or continuous motion.[0005]More specifically, the seal banding machines that operate with continuous motion comprise means which apply the sealing band to the lateral surface of a carton and which have a surface for retaining and supporting the sealing band, and means designed to rotate the container body while the latter's lateral surface engages the peripheral surface of the means which apply the sealing band.[0006]Thus, prior art seal ...
