Abstract

The invention relates to apparatus for simultaneously feeding a machine with webs of material from a plurality of web supply rolls, the rolls being mounted in tandem with their winding axes parallel to one another between roll stands situated opposite one another in pairs, and a loading car for carrying new rolls which runs between the bilateral roll stands. To hasten the roll changing procedure, the loading car is capable of receiving simultaneously the entire number of mountable rolls with a spacing between them corresponding to the spacing of the successive roll mounting axes. For this purpose, there are provided automatically operating means for carrying away the roll cores released from the respective roll stands, and means for holding the ends of the indrawn webs of material which can be lowered automatically onto the circumferencial surfaces of the web rolls, and which are combined with means for severing the respective webs of material. A roll preparation section with a loading station is preferably provided ahead of the track carrying the loading car.

Dependent claims

Apparatus for feeding a machine with a plurality of webs of material from a plurality of web supply rolls, said apparatus comprising, in combination:

(a) a plurality of roll stands, positioned opposite one another in pairs, each pair being adapted to rotatably support a single web supply roll, said roll stands being arranged to support a plurality of rolls with the pool axes in parallel;
(b) a loading car for carrying rolls, arranged to run between the roll stands on both sides and capable of receiving simultaneously the entire number of the rolls which can be mounted in the apparatus, with the spacing of the respective rolls corresponding to that of the successive roll mounting axes in said roll stands;
(c) means for removing the roll cores released from said roll stands;
(d) means, disposed above the rolls mounted on said roll stands, for temporarily holding the ends of the webs of material drawn into the machine during a roll change operation;
and
(e) a web supply roll preparation section including:
(1) a plurality of successive roll preparation stations arranged adjacent the path of travel of said loading car for the individual preparation of new web supply rolls;
and
(2) a loading car loading station following said roll preparation stations in succession, for successive transfer of the prepared rolls onto said loading car.
