Problems solved by technology

This results in higher energy consumption and excessive heating of the material
In addition, brief stops of the machine, e.g. when adjusting the cutting width or when changing coils etc., lead to a stronger cooling of the heated edges than in normal continuous automatic operation because the joining cycle is interrupted

Embodiment Construction

[0024] FIG. 1 shows a joining device 1 according to the invention in a schematic diagram, wherein only the main components necessary for explaining the invention are shown here. A joining tool 2 is shown consisting of an upper tool 3 in the form of a joining bar 4 which is movable vertically (see double arrow A) and a stationary lower tool 5 in the form of a joining table 6 . The joining table 6 supports the two strip sections 7 , 8 to be joined, which overlap in their edge regions as shown in FIG. 1 . The belt section 7 has already been joined to an endless belt in a previously performed joining process, ie forms the end of the endless belt. The strip section 8 has been conveyed by a feed device (not shown in detail) by a cutting device (not shown in detail) and is superimposed with its leading edge on the trailing edge of the strip section 7 . For the joining, the joining strip 4 is now moved downwards and presses the two overlapping strip edges against each other and is su...

Abstract

Heaters (9, 10) are associated with the jaws of the splicing equipment (1). The strip sections (7, 8) are spliced between upper and lower jaws of the tool, heaters being included in either or both of them. Their heating is direct or indirect, using an electrical resistance heater, a radiant heater or a hot air blower. Electrical resistance heaters are located on, in or adjacently to the upper and lower jaws of the splicing tool The heaters comprise heating strips, cartridges or flat heaters. The jaws are heated by an indirect heater whilst in a resting position. They move relative to the belt, from this position to a splicing position. A number of heaters are arranged in parallel and / or in series, over the width of the splicing tool jaws. The power supplied to each heater is individually-controllable. Sensors relay measured values of jaw temperatures to the heater controller, which uses them in controlling the splicing operation.

Description

technical field [0001] The invention relates to a joining device for joining unvulcanized or prevulcanized belt sections made of rubber material, in particular fabric or steel cord belts, comprising a Splicing tool (Spleiβwerkzeug) on ​​the spliced ​​belt sections. Background technique [0002] Splicing devices of the described type are mainly used in the tire industry and for producing endless belts from cut belt segments, especially in the form of belt segments of textile cords or steel cords. The belt sections are made of unvulcanized or prevulcanized rubber material, which forms the load-bearing matrix. A fabric or steel cord gusset is usually built into the rubber material. The previously cut strip sections are joined by means of a joining device or a joining tool arranged on the device side in an overlapping or abutting manner, ie are firmly connected to one another, which is made possible due to the adhesive properties of the rubber material. Various joining tools ...
