Definitions

the present invention relates to means designed for transfering a roll of material onto a tenter during unwinding, and in particular regards a cradle support for rolls without support posts or shafts.
a cradle support able to transfer a roll of material and make it rotate on its axis for the unwinding of the material is already available.
Such a cradle support has a V-shaped transverse configuration and is formed by ribbons placed side by side which are driven on parallel horizontal rollers positioned at various levels.
the known cradle supports have the following disadvantages:
the present invention aims to eliminate the above mentioned problems and provide a cradle support with variable position for a more advantageous, practical and easy use.
the here proposed cradle support is substantially in accordance with claim 1. It has a V-shaped transverse configuration made up of a single series of continuous ribbons placed side by side, forming the two arms of the V-shape, that is to say a belt conveyor with an ascending and a descending arm due to a particular and specific placement of the driving and transmission rollers. Also, one of the arms of the cradle has a variable inclination so as to be able to correspondingly modify the opening angle of the cradle in accordance with the roll fitted.
the arm can also be brought to a horizontal position, thus making the loading and unloading of the rolls much easier through an appropriate advancement of the belt conveyor made up of ribbons.
the mentioned cradle support (10) is designed to hold a roll of material (11) ready to unwind in the direction of the arrow (F).
Said cradle support (10) comprises a structure with two shoulders (12) between which a belt conveyor (13) is placed.
Said belt conveyor having a V-shaped transverse configuration and made up of a number of ribbons (14) positioned side by side and driven on parallel rollers fitted between the shoulders (12) at various heights.
said ribbons (14) are driven on a set of three central rollers (15, 15a, 15b) which are in a fixed position and form a V-shape. They then go up and pass over an upper fixed roller (16) then descend and pass over a lower fixed roller (17) where they turn back, beneath the set of three rollers (15, 15a, 15b) to the opposite side, passing over a movable roller (18) with variable positions, then returning towards the set of three central rollers.
At least one of the fixed rollers (16) or (17) is driven in rotation by a motor (not shown) for the controlling of the advancement of the belt conveyor (13), the direction of which is shown by the arrow ( S ) for the unwinding of the material.
the direction can be changed.
An idler (19) is coordinated on the lower arm of the belt conveyor which extends from the lower fixed roller (17) on the side towards which the material unwinds, to the movable roller (18) on the opposite side.
the movable roller (18) is carried by oscillating arms (20) which, for example, move on the axis of the roller (15a) of the centre three rollers and is engaged by a movement actuator (21) (Fig. 2).
the idler (19) is fitted on said oscillating arms (20) so that it is correspondingly positioned and always keeps the correct tension of the ribbons even, when changing the position of the movable roller (18).
This movable roller can infact be positioned above due to an angular movement of its oscillating arms (20) by the use of the actuator (21). In this way, the general position of the cradle can be varied by changing the opening angle between the ascending and descending arms of the belt conveyor from time to time, this belt conveyor being between the movable roller (18) and the upper fixed roller (16) and is defined at the top by the set of three rollers (15, 15a, 15b).
the position of the cradle support can in this way be adjusted to every need and in accordance with the rolls of material fitted.
the movable roller can be moved below until one of the arms of the V-shaped belt conveyor reaches a horizontal position, (Fig. 1), so as to help the loading and unloading of the rolls through the movement of the belt conveyor, even in the opposite direction of the arrow ( S ) during the unloading of the rolls.
