Problems solved by technology

[0002] It is known that during the production of shoes there is the problem that the surface for bonding must first be roughened in order to increase the adhesion of said bonding
In fact, the roughing operation generates dust, which must be carefully removed from the shoe before applying the adhesive, since this dust deposited on the surface of the shoe will bond with the surface of the shoe on which the adhesive is applied. The adhesive creates a barrier between itself, thereby reducing the effectiveness of the adhesive and the final bond quality
However, the cleaning step slows down the machining operation and does not always fully achieve the desired result

Embodiment Construction

[0029] With reference to the accompanying drawings, figure 1 An apparatus, generally indicated at 10 , applying the principles of the invention is shown schematically.

[0030] This plant comprises a device according to the invention for preparing the shoe for subsequent bonding, wherein the roughing tool (advantageously rotating) is coated or impregnated with the adhesive by means of a dispensing system. Thus, the device roughens the shoe while, due to the movement and / or rotation of the roughing tool, an appropriate amount of adhesive is applied to the roughened surface before the adhesive dries.

[0031] The device 10 is equipped with automation means for the programmed movement on the surface of the shoe. Advantageously, this device preferably comprises a processing head 11 and a support 12 for a shoe 13 . The machining head 11 and the support 12 are movable relative to each other by means of a drive which causes the machining device (indicated by 14) to run along a desi...

Abstract

The invention discloses a method, a device and a machine for processing shoes. The method for preparation of a part of a surface of a shoe for subsequent gluing comprises the steps of spreading a glue on the operating surface of a roughing tool and applying this operating surface onto the part of the shoe to be roughed before drying of the glue, so as to transfer the glue onto the part of the surface being roughed. A device (14) implementing this method and a machine (10) using this device are also described.

Description

technical field [0001] The present invention relates to a method, apparatus and apparatus for roughening parts of a shoe and applying adhesive to these parts. Background technique [0002] It is known that in the production of shoes there is the problem that the surface for bonding must first be roughened in order to increase the adhesion of said bonding. This means that the shoe has to go through two consecutive processing steps, which however usually have to be perfectly bonded to the shoe at the end of the shoe processing operation in order to avoid poor bonding or visible defects. [0003] In particular, the invention can be advantageously carried out on the following processing steps for shoes: the step of the side of the shoe which needs to be roughened near the bottom, and the step of applying adhesive to said roughened part, which is roughened. The thickened part is used to fix the sole and the side later. [0004] These steps are especially important for many type...
