Abstract:
1. A device for turning up a tire-building component disposed on a tire-building drum, the device comprising: a roller lever; at least one roller rotatably mounted at one end of said roller lever; a segment disposed opposite said roller lever, said roller lever being movable with respect to said segment; a spacer spacing said at least one roller and said segment apart from one another during a process of preparing a turning up, such that during said process of preparing a turning up, said at least one roller is in contact with, and rolls along, a tire-building component, but does not contact said segment; and said spacer including a cam at said one end of said roller lever and a cam on said segment disposed opposite said roller lever, said cams sliding on one another to maintain a gap between said at least one roller and said segment during said process of preparing the turning up so that said at least one roller is essentially in contact only with the tire-building component resting on it, as a result of which said at least one roller rolls along the tire-building component in a single rotational direction so that the at least one roller does not push the material of the tire-building component forward.
