Definitions
- the invention relates to a method as defined in claim 1 and to a device as defined in the preamble of claim 8 for protecting core material with protective material.
- ribbon-type materials as a mechanical, interference and humidity protection between core material, e.g. a cable core, and top material.
- core material e.g. a cable core
- top material e.g. a mechanical, interference and humidity protection between core material, e.g. a cable core, and top material.
- the delivery ribbon lengths of ribbon-type protective materials are shorter than e.g. the production length of a completed cable, which is due to the manageability of protective material reels and to the logistics associated with their manufacture and transportation. Big reels are hard to handle and their storage can be cumbersome.
- the diameter of ribbon reels is usually no more than 1000 mm, which limits the delivery lengths of protection material to about 2000 meters.
- the prior-art technology has the problem of making the joint while the process is still going on.
- One specific objective of the present invention is to disclose a new type of method and device for protecting core material, e.g. in a cable manufacturing process .
- the invention is based on a method for protecting core material by means of protective material, in which method the core material is coated with pro- tective material in a manufacturing process.
- step of spooling the protective material ribbon a uniform, cut-to-size protective material ribbon is un-spooled from one or more protective material ribbon reels onto the rolling-up unit.
- ribbons from different reels are joined together by their ends to manufacture a desired, cut-to-size protective material ribbon so that the far end of a ribbon from a first protective material reel is joined together with the front end of a ribbon from a second protective material reel to achieve a uniform protective material ribbon.
- the joint between two ribbons is tested and its quality ensured at the step of spooling.
- the rolling-up unit having a ribbon length of protective material necessary in the coating of the core material, is removed at the step of trans- ferring and is transferred to the step of coating the core material .
- the protective material ribbon is guided from the rolling-up unit simultaneously with the core material to a device in which the core material is ar ⁇ ranged within the protective material ribbon.
- the protective material ribbon is bent so as to enclose the core material .

- a protective material ribbon reel in the reel station can be replaced with a new one.
- the protective material ribbon is arranged to pass from the protective material ribbon reel via the jointing device to the rolling-up unit.
- the far end of a ribbon from the first protective material reel can be joined together with the front end of a ribbon from the second protective material reel, if necessary, to achieve a uniform ribbon.
- a protective material ribbon having the length of the core material is arranged in the rolling-up unit.
- the core material may have been arranged to have a cable-like, wire-like, ribbon-like or similar form.

- the pallet may have been provided with a place for the forklift spikes.
- the conveyor pallet may also be a so-called automatic guided vehicle.
- the ribbons in the jointing device of the spooling device, can be joined to one another by welding. It is possi- ble to use e.g. soldering or laser welding. Preferably, the joint is formed prior to the step of coating the core material .
- the spooling device also includes quality checking means.
- the quality of the cut-to- size protective material ribbon to be spooled onto the rolling-up unit and the quality of the joint in the ribbon are checked before the ribbon is spooled onto the roll of the rolling-up unit. Then the possible er- rors in the ribbon and in the joint are detected.
- the quality checking means are arranged in conjunction with the jointing device.

- the method and device of the invention have significant advantages compared to the prior art.
- the spooling of protective material ribbons onto a bigger unit and the jointing procedure of the ribbons are performed as their own separate phases.
- To the step of coating the core material one feeds a protective material ribbon that has already been cut to size and also quality- checked.
- the invention has the advantage that in forming the ribbon length of the roll of the rolling-up unit it is possible to make use of even shorter stretches of protective material ribbons to achieve the desired ribbon length, enabling one to make use of the remaining ribbons of the protective material ribbon reels. In that case, one has the advantage of smaller material losses. Thanks to the method of the invention, it is possible to make several joints because jointing in a separate phase as defined in the invention is not a risky phase in the process. Furthermore, in the method of the invention, it is possible to perform the quality checking of the joints substantially in conjunction with the jointing procedure.
- the invention enables one to feed to the coating process of core material a protective material ribbon having exactly the right length as the process is concerned.
- the invention enables one to achieve a continuously operating, reliable and high- quality coating method of core material quickly, easily and with reduced cost.
- the rolling-up unit can be connected to the coating device of core material with just some minor changes.
- the invention enables one to reduce the space requirement of the coating process of core material because the jointing process of protective material ribbons can be performed as a separate process in a suitable place. Furthermore, the rolling-up unit of protective material can be placed into any desired parallel coating line of core material . This enables one to optimise the manufacturing process.
- the method and device of the invention can be used e.g. in cable manufacturing industry.
