Winding machine for winding lengths of material
The invention relates to a winding machine for winding material webs, in particular foils or films, wherein the winding machine comprises a feeder system with a first belt feeder which, during the winding of the material web around a winding core in a first direction, wraps itself at least partially around the material web. The feeder system comprises a second belt feeder which is suitable for winding the material web in a second direction around the winding core.
1. A winding machine with a feeder system for winding a material web of foil or film around a winding core, comprising:
at least one circulating belt;
a first belt feeder constructed and arranged to wrap the at least one circulating belt at least partially around the material web during a winding of the material web around the winding core in a first direction; and
a second belt feeder constructed and arranged to wind the material web in a second direction around the winding core;
wherein the first and the second belt feeders each comprise at least two levers, and wherein the levers have head ends and further include pressure elements arranged, respectively, in a region of the head ends of the levers.
2. The winding machine according to claim 1 , wherein the levers of the first belt feeder are two-sided and centrally positioned.
3. The winding machine according to claim 1 , further including two coupling links coupled to the levers of the second belt feeder to limit a pivoting movement of the levers of the second belt feeder.
4. The winding machine according to claim 1 , wherein the first belt feeder comprises two-sided, centrally positioned levers and the second belt feeder comprises levers that are positioned via two coupling links to limit a pivoting movement of the levers of the second belt feeder.
5. The winding machine according to claim 1 , wherein the winding machine includes a frame and the feeder system is pivotally arranged on the frame of the winding machine.
6. The winding machine according to claim 1 , wherein the at least one circulating belt comprises is guided circulating on the first belt feeder and the second belt feeder.
7. The winding machine according to claim 6 , wherein the at least one circulating belt is guided between respectively the at least two levers of the first belt feeder and the at least two levers of the second belt feeder.
8. The winding machine according to claim 6 , wherein the at least one circulating belt comprises an endlessly circulating belt.
9. The winding machine according to claim 1 , further including separate adjustment devices coupled to the first and second belt feeders to separately adjust a pivoting position of the first and second belt feeders.
10. The winding machine according to claim 1 , wherein the at least two levers of the first belt feeder have a first pivoting point around which the at least two levers of the first belt feeder are pivotable, and the at least two levers of the second belt feeder have a second pivoting point around which the at least two levers of the second belt feeder are pivotable, and further including one rotating roll which deflects the at least one circulating belt arranged between the at least two levers of the first belt feeder.
11. The winding machine according to claim 1 , wherein the at least two levers of the first belt feeder have a first pivoting point around which the at least two levers of the first belt feeder are pivotable, and the at least two levers of the second belt feeder have a second pivoting point around which the at least two levers of the second belt feeder are pivotable, and further including one rotating roll which deflects the at least one circulating belt arranged between the at least two levers of the second belt feeder.
12. A winding machine with a feeder system for winding a material web of foil or film around a winding core, comprising:
at least one circulating belt;
a first belt feeder constructed and arranged to wrap the at least one circulating belt at least partially around the material web during a winding of the material web around the winding core in a first direction; and
a second belt feeder constructed and arranged to wind the material web in a second direction around the winding core;
wherein the first and the second belt feeders each comprise at least two levers, wherein the levers of the first and second belt feeders have head ends and further including rotating deflection rolls arranged on the head ends of the levers of the first and second belt feeders.
13. The winding machine according to claim 12 , wherein the at least one circulating belt is deflected by the deflection rolls.
14. A winding machine with a feeder system for winding a material web of foil or film around a winding core, comprising:
at least one circulating belt;
a first belt feeder constructed and arranged to wrap the at least one circulating belt at least partially around the material web during a winding of the material web around the winding core in a first direction; and
a second belt feeder constructed and arranged to wind the material web in a second direction around the winding core;
wherein the first and the second belt feeders each comprise at least two levers, wherein the levers have head ends and further include pressure elements arranged, respectively, in a region of the head ends of the levers, and wherein the pressure elements comprise spring plates.
