Disclosed herein is a high release nip roll assembly comprising a nip roll with a covering comprising a high release material. The release properties of the nip roll material can permit intermittent contact without the coating adhering to the surface of the roller and wrapping the nip. Also disclosed is a high release nip roll belt is made of a high release material on the top and bottom surfaces of the belt. The belt can be positioned at each end of a nip roll so that areas of the nip roll typically vulnerable to molten thermoplastic material contact are protected by a belt. Also disclosed is a belt making apparatus. Also disclosed is a frame assembly for moving a belt longitudinally along a nip roll. Also disclosed is a rope guide assembly for threading a belt in relation to a nip roll and at least at least one belt roller.
A belt comprising a first tape and a second tape, each tape having a high release side, and an adhesive side, wherein the adhesive side of each tape is joined to the adhesive side of the other tape, with the side edges of the tapes aligned so that top and bottom surfaces of the belt comprises the high release sides of each tape, the belt comprising a leading section and wherein a portion of the first tape has been removed at the leading section, thereby exposing a portion of the adhesive side of the second tape at the leading section, the belt comprises a trailing section and wherein a portion of the second tape has been removed at the trailing section, thereby exposing a portion of the adhesive side of the first tape at the trailing section, wherein the portion of the exposed adhesive side of the first tape at the trailing section is adhered to the portion of the exposed adhesive side of the second tape at the leading section to form a closed belt.
An apparatus comprising a nip roll having a high release material cover, and a high release belt comprising a first tape and a second tape, each tape having a high release side, and an adhesive side, wherein the adhesive side of each tape is joined to the adhesive side of the other tape, with the side edges of the tapes aligned so that top and bottom surfaces of the belt comprises the high release sides of each tape and wherein a portion of the belt is positioned on the nip roll to protect the nip roll at a location that otherwise would be vulnerable to molten thermoplastic material.
A belt making apparatus comprising a wind-up drum, a first tape roll having a first tape, the first tape having a high release side and an adhesive side, and a second tape roll having a second tape, the second tape having a high release side and an adhesive side, the wind-up drum defining a slot, the wind-up drum comprising a first clamp and a second clamp inside the wind-up drum, wherein the first tape from the first tape roll can be fed into the slot and clamped by the first clamp, and the second tape from the second tape roll can be fed into the slot and clamped by the second clamp, wherein the wind-up drum can be rotated and the adhesive side of the first tape adheres to the adhesive side of the second tape as the tapes are wound around the outside of the wind-up drum, thereby producing a high release belt having a high release surface on each side of the belt.
An apparatus comprising at least one belt roller, the belt roller having an axis, and a support frame having a fixed portion and a moveable portion, the fixed portion comprising a fixed support bar having a section that is parallel to the axis of the belt roller and upon which the moveable portion can move along, the belt roller attached to the moveable portion of the support frame.
An apparatus comprising a rope guide system having a closed loop of rope and at least one rope guide for guiding the rope in a path in relation to a nip roll and at least one belt roller, wherein the rope can be attached to a leading section of a belt, wherein the rope can be pulled around the at least one rope guide so that the rope pulls the belt in a predetermined path around at least one belt roller, the rope being detachable from the leading section of the belt after sufficiently threading the leading section of the belt in relation to a nip roll and the at least one belt roller, and the leading section of the belt can be joined to the trailing section of the belt.
An apparatus comprising a jig for joining a leading section of belt and a trailing section of a belt, the jig comprising a top surface, the top surface defining a channel having a predetermined belt width, a leading section belt clip on one side of the curved arc top surface, and a trailing section belt clip on the other side of the curved arc top surface, wherein a leading section of a belt can be clipped to the jig by the leading section belt clip, and laid within the channel, and the trailing section of the belt can be clipped to the jig by the trailing section belt clip, wherein an adhesive side of a bottom tape of the leading section of the belt can be exposed, an adhesive side of the top tape of the trailing section of the belt can be exposed to, aligned with, and adhered to the adhesive side of the bottom tape of the leading section of the belt.
