Abstract
A method of removing ties and a wrapper from a fiber bale being at least partially covered by the wrapper and surrounded by the ties tightened about the wrapper includes the steps of severing the ties; carrying the ties away from the bale and pulling the wrapper off the bale in several parts after the ties are carried away from the bale.
Claims20
A method of removing ties and a multi-part wrapper from a fiber bale having a circumferential surface portion uncovered by the multi-part wrapper and being surrounded by the ties tightened about the wrapper, comprising the following steps:
- (a) severing the ties at the uncovered surface portion of the bale;
- (b) carrying the ties away from the bale after step (a);
- and
- (c) pulling the wrapper parts of the multi-part wrapper off the bale separately from one another after step (b).
An apparatus for removing ties and a wrapper from a fiber bale, comprising:
- (a) supporting means for positioning the fiber bale;
- (b) a severing device disposed at said supporting means for severing said ties;
- (c) a tie-removing device disposed at said supporting means for removing the severed ties from the bale;
- and
- (d) a pull-off device for removing the wrapper from the bale;
- said pull-off device including
- (1) a pull-off roll;
- (2) pull-off teeth carried on said pull-off roll;
- (3) means for rotating said pull-off roll;
- and
- (4) rotary bearing means for supporting said pull-off roll at one end thereof.
An apparatus for removing ties and a wrapper from a fiber bale, comprising
- (a) supporting means for positioning the fiber bale;
- (b) a severing device disposed at said supporting means for severing said ties;
- (c) a tie-removing device disposed at said supporting means for removing the severed ties from the bale;
- and
- (d) a pull-off device for removing the wrapper from the bale;
- said pull-off device including
- (1) a pull-off roll including
- (i) pull-off teeth carried on said pull-off roll;
- (ii) a cylindrical shell provided with apertures constituting passages for said pull-off teeth;
- and
- (iii) tooth-moving means accommodated in said cylindrical shell for placing said pull-off teeth into a first position in which the pull-off teeth project through said apertures from said cylindrical shell and a second position in which said pull-off teeth are withdrawn into said cylindrical shell;
- and
- (2) means for rotating said pull-off roll.
A method of removing ties and a wrapper from a fiber bale being at least partially covered by the wrapper and surrounded by the ties tightened about the wrapper, comprising the following steps:
- (a) severing the ties;
- (b) carrying the ties away from the bale after step (a);
- and
- (c) pulling the wrapper off the bale in several parts after step (b);
- said pulling step including the steps of causing two wrapper pull-off devices to penetrate the wrapper parts at a vertical end face of the bale, moving one of the pull-off devices vertically upwardly beyond a top face of the bale and moving the other of the pull-off devices vertically downwardly beyond a bottom face of the bale.

- and
- (d) a pull-off device for removing the wrapper from the bale;
- said pull-off device including
- (1) a pull-off roll;
- (2) pull-off teeth carried on said pull-off roll;
- (3) means for rotating said pull-off roll;
- and
- (4) roll-supporting means for displaceably supporting sad pull-off roll;
- said roll-supporting means including bearing means for permitting a pivotal motion of said pull-off roll in a vertical plane.
