Abstract
A method for supplying fibres to a filling tool in brush manufacturing machines, includes, per operating cycle, taking a bundle of fibres (7) from a selected fibre supply duct (4,5) to the filling tool (3) by means of a bundle take-up device (6) which cooperates with at least two fibre ducts (4,5), and using, for the selective supply of the fibres (2-2A), moveable closing devices (19,20) which cooperate with the supply ends (11,12) of the fibre ducts (4,5) and which ensure, by their movement that fibres (2-2A) can only be taken from one fibre duct (4,5) at a time by the bundle take-up device. The closing devices (19,20) are mounted on a common support for simultaneous movement each cycle.
Claims19
A method for cyclically supplying fibres to a filling tool in a brush manufacturing machine including at least two fibre supply ducts having supply ends for supplying bundles of fibres to a fibre bundle take-up device that cyclically transports the fibre bundles to a brush body filling tool comprising, for each machine operating cycle;
- transporting a bundle of fibres taken from a selected one of the at least two fibre supply ducts to the filling tool by means of the bundle take-up device that cooperates with the fibre supply ducts;
- and
- cyclically opening and closing the fibre supply ducts by blocking devices interconnected in fixed relationship with respect to each other mounted on a unitary movable support during movement of the fibre bundle take-up device, whereby the other of the fibre supply ducts not supplying fibres to the fibre bundle take-up is closed off while the fibres are supplied from the selected one fibre supply duct to the bundle take-up device.
A method for supplying fibres to a filling tool in brush manufacturing machines, comprising, for each operating cycle, transporting a bundle of fibres from a selected one of a pair of fibre supply ducts to a filling tool by means of a bundle take-up device that moves along a path of travel between a filling tool and a pair of fibre supply ducts located at spaced points along the path of travel of the bundle take-up device, said bundle take-up device including a fibre bundle receiving recess, and varying the travel distance of the bundle take-up device as a function of the location of the fibre supply duct from which the fibres are to be supplied, said recess being moved during each take-up of fibres so as to only travel to the respective fibre supply ducts and not to a further fibre supply duct than the fibre supply duct from which the fibres are to be taken.
Apparatus for cyclically supplying fibres to a brush body filling tool in a brush manufacturing machine comprising:
- at least two fibre supply ducts;
- a movable fibre bundle take-up device arranged to move along a path of travel between a filling tool and one or the other of the at least two fibre supply ducts to receive a bundle of fibres from said one or other fibre supply duct each cycle of operation of the machine;
- and
- a blocking means associated with each supply duct for blocking the fibre supply duct not supplying fibres to said bundle take-up device while the bundle take-up device is receiving fibres from another fibre supply duct;
- said blocking means being mounted in fixed relationship with each other on a common movable support for simultaneous movement with the support;
- and
- means for cyclically moving the movable support to actuate the blocking means.
Apparatus for cyclically supplying fibres to a brush body filling tool in a brush manufacturing machine comprising:
- at least two fibre supply ducts;
- a fibre bundle take-up device movable along a path of travel extending between a filling tool and said fibre supply ducts;
- said fibre supply ducts located at spaced points along the path of travel of said bundle take-up device;
- said bundle take-up device arranged to approach one or the other of the at least two fibre supply ducts to receive a bundle of fibres from said one or other fibre duct each cycle of operation of the machine;
- and
- means for controlling the travel distance of said bundle take-up device such that the take-up device only traverses a distance extending from the filling tool to the one fibre supply duct from which it is to receive fibres each operating cycle of the machine.
