Abstract

An apparatus for conveying a textile product from an upstream to a downstream station, especially for delivery into a package, has an endless conveyor belt driven by a drive and a pressure unit, the textile product being conveyed while held in a gripped manner between conveyor belt and pressure unit. To achieve rapid conveyance of the textile product without thereby impairing it, it is proposed that the conveyor belt be configured as a first telescoping belt, the front end of which, facing the downstream station, can move back and forth in the direction of the downstream station while the pressure unit follows this motion synchronously; and that the drive be controlled so that the belt of the telescoping belt is not driven as the front end moves back from the downstream station, and thereby rolls off the textile product.

Claims

1. Apparatus for conveying a textile Product from an upstream station to a downstream station, in particular for delivering a textile product into a package, said apparatus comprising:

drive means driving a first telescoping belt means comprising a first belt part of which extends in a first direction between a downstream station and an upstream station., said first telescoping belt means further comprising a first front end facing said downstream station, said first belt being guided around said first front end which is arranged for movement back and forth either backwards towards said upstream station or forwards towards said downstream station;

second telescoping belt means comprising a second belt part of which extends in said first direction parallel to said part of said first belt, said second telescoping belt means further comprising a second front end facing said downstream station, said second belt being guided around said second front end which is arranged for movement back and forth;

wherein

said first and second belts are arranged at such a distance from each other that a textile product may be conveyed between both belts while being enclosed between both belts;

said first and said second front ends are arranged for synchronous motion back and forth in said first direction; and

said drive means is controlled such that said first and second belts are not driven when said first and second front ends are moved simultaneously backwards in said first direction, thereby releasing said textile product.

2. Apparatus according to claim 1, which further comprises:

two stationary first reversing rollers spaced apart from one another comprising a first front stationary reversing roller and a first rear stationary reversing roller;

a first slide adapted for moving back and forth in said first direction, said first slide having a first front reversing roller and a first rear reversing roller;

wherein

said first front reversing roller of said first slide comprises said first front end;

said first rear reversing roller of said first slide is arranged between said two first stationary reversing rollers; and

said first belt is guided around said first rear stationary reversing roller to said first front reversing roller, around said first front reversing roller to said first rear reversing roller, around said first rear reversing roller to said first front stationary reversing roller and back to said first rear stationary reversing roller.

3. Apparatus according to claim 1, wherein said drive means is controlled such that as said first front end moves forwards in said first direction also said first belt moves forwards in said first direction.

4. Apparatus according to claim 2, which further comprises:

two stationary second reversing rollers spaced apart from one another comprising a second front stationary reversing roller and a second rear stationary reversing roller;

a second slide adapted for moving back and forth in said first direction, said second slide having a second front reversing roller and a second rear reversing roller;

wherein

said second front reversing roller of said slide comprises said second front end;

said second rear reversing roller of said slide is arranged between said two second stationary reversing rollers;

said second belt is guided around said second rear stationary reversing roller to said second front reversing roller, around said second front reversing roller to said second rear reversing roller, around said second rear reversing roller to said second front stationary reversing roller and back to said second rear stationary reversing roller;

said first telescoping belt means and said second telescoping belt means are constructed identically and are arranged mirror symmetrically to one another.

5. Apparatus according to claim 1, which further includes an adjusting means for adjusting the distance between said first and said second belts.

6. Apparatus according to claim 4, which further includes a chassis supporting the first and second stationary reversing rollers, and wherein said first and said second belts are both driven by said drive means.

7. Apparatus according to claim 2, wherein said first slide further includes a first guide plate extending along said first direction, said first guide plate holding said first front reversing roller at one end thereof, said first front reversing roller having a diameter which approximately corresponds to the thickness of said guide plate.

8. Apparatus according to claim 4, wherein said second slide further includes a second guide plate extending along said first direction, said guide plate holding said second front reversing roller at one end thereof, said second front reversing roller having a diameter which approximately corresponds to the thickness of said guide plate.

9. Apparatus according to claim 8, wherein said first and second guide plates comprise rear ends being adjacent said first and second rear stationary reversing rollers when said guide plates are in their rearmost positions.

10. Apparatus according to claim 8, wherein each of said guide plates is provided with edge rails, said edge rails extending along said first direction for guiding said first or second belt therebetween.
