Abstract
A carpet rolling machine for quickly and efficiently rolling carpet around a core without causing damage to the carpet. The machine includes a moveable dispenser for applying an adhesive flap to the core prior to winding the carpet around the core. The leading edge of the carpet is positioned between the flap and the core so that it may attach to the adhesive on the interior surface of the flap. Once the leading edge of the carpet is properly positioned, the carpet is wound around the core by a roll up.
Claims12
A device for winding an elongate strip of flexible material having a leading edge around a roll, said device comprising a flap applicator which applies a flap to a core;
- and a roll up which feeds the leading edge of the flexible material between the flap and the core and winds the elongate strip of flexible material around the core;
- wherein the flap applicator comprises:
- (a) a carriage assembly which rides on wheels via a frame and track assembly;
- (b) a carriage drive unit which drives the carriage via a drive gear and drive rack;
- (c) a roll of tape connected to the flap applicator carriage assembly which feeds the flap onto a flap applicator roll which moves across the length of the core applying the flap to the core;
- and
- (d) a pair of actuators which retract to move the position of a pair of linkages attached to frame and track attachment arms, thereby moving the applicator across the width of the core.
A device for winding an elongate strip of flexible material having a leading edge around a roll, said device comprising a flap applicator which applies a flap to a core;
- and a roll up which feeds the leading edge of the flexible material between the flap and the core and winds the elongate strip of flexible material around the core;
- where the roll up comprises:
- (a) a drive roll and a tuck roll which hold the core with the flap attached;
- (b) a starting head which travels along a starting head guide until it rests on top of the drive roll and tuck roll;
- (c) a turning bar mounted above a lift pan, positioned between the drive roll and the tuck roll, which positions the core and the flap to receive the leading edge of the flexible material and guides the flexible material as it is being fed into the q roll up.
A rolling machine having a loading deck, a frame over a cutting table, and a flap core positioning system comprising:
- (a) a core dispenser mounted to the frame;
- (b) a core placement arm mounted to a core placement head;
- and
- (c)a flap applicator mounted proximate to the core placement head.
A method for winding an elongate strip of flexible material into a roll around a core with a flap attached, said method comprising:
- (a) attaching a flap to a core by moving a flap applicator along the length of the core;
- (b) inserting a leading edge of the flexible material between the flap and the core by:
- (i) positioning the core with flap attached on a drive roll and a tuck roll of a roll up;
- (ii) raising a turning bar to lift the core off at least one of the drive roll and the tuck roll;
- (iii) moving a starting head into position above the core;
- and
- (iv) feeding the leading edge of the flexible material into the roll up and across the turning bar;
- and
- (c) rolling the material around the core.
In a rolling machine of the type having a squaring table, a core dispenser and a roll up, a flap applicator comprising:
- (a) a lateral track;
- (b) a laterally moveable carriage assembly connected to the lateral track holding a roll of tape with a fastening mechanism;
- (c) a tape cutter;
- and
- (d) a longitudinally adjustable linkage connected to said lateral track.
A method of winding flexible material about a core in a rolling machine of the type having a squaring table, a core dispenser, and a roll up with a drive roll, a tuck roll, and a turning bar comprising the steps of:
- (a) dispensing a core;
- (b) positioning said core having a flap over the drive roll and the tuck roll;
- (c) positioning the turning bar proximate the tuck roll and beneath the core;
- (d) feeding a leading edge of the flexible material into the roll up, and upwards between the drive roll and the turning bar;
- (e) continuing to feed the leading edge of the flexible material into a mouth formed between the flap and the core;
- (f) driving the drive roll and the tuck roll in the same direction to wind the flexible material about the core.
A roll up for winding an elongate strip of flexible material comprising:
- (a) a drive roll;
- (b) a tuck roll extending parallel to the drive roll and having a space there between;
- (c) a turning bar extending parallel to the drive roll and being moveable in a vertical direction within the space and being moveable in a horizontal direction from a first position proximate the drive roll to direct the elongate strip to contact the tuck roll to a second position proximate the tuck roll to direct the elongate strip to contact the drive roll;
- (d) a starting head moveable from an operating position over and proximate to the drive roll and tuck roll, to a resting position relatively distal from the drive roll and tuck roll.
