摘要:
A method and apparatus is provided for feeding envelopes (28) in a linear array between upstanding conveyor flights (32) and for transferring the envelopes (28), a batch at a time, to en elevated position for removal to a next processing station. Envelopes (28) are subsequently received in a receiving cradle (150) at the elevated transfer station (24) and are carried downwardly to a lower exit station where the batch of envelopes (28) is discharged to a receiving bin.
摘要:
A process is provided for the opening of envelopes made of cellulosic paper in which there is applied to at least one envelope edge as the sole reactant with the cellulose therein a non-noxious organic acid having at least one pK value at room temperature between about 1.5 and about 5, followed by the application of heat and mild mechanical action to the envelope edge.
摘要:
In an envelope opening process in which an aqueous solution of a chemical degradation agent, such astartaric acid is applied to envelope edges and the envelope edges are then heated and subjected to a mild mechanical action, penetration of the degradation agent through the envelope paper at its edges is assured by including in the aqueous solution from 2.5% to 30% of a glycol ether, such as ethylene glycol ethyl ether.

摘要:
A method and apparatus is provided for transferring a batch of envelopes that have been arranged in face-to-face relationship. The envelopes (28) are transferred in a substantially horizontal plane from a first location (26) to a second location (20) spaced from the first location. The apparatus (24) includes a pair of downwardly depending spaced-apart members (124,126) which are each adapted to contact the batch (28) of envelopes along the end edges of the envelopes. One (124) of the paddles (124,126) is adapted to urge a batch (28) along a guide channel (100) from the first position (26) to the second position (20). The other (126) of the paddles (124,126) is adapted to urge a batch (28) along the guide channel (100) in the opposite direction from the second position (20) to the first position (26).
摘要:
Procede pour l'ouverture d'une enveloppe en papier cellulosique dans lequel on applique au moins sur une bordure de l'enveloppe, comme seul agent de reaction avec la cellulose, un acide organique non deletere ayant au moins une valeur de pK a temperature ambiante entre 1,5 et 5 environ, apres quoi on applique de la chaleur et on exerce une legere action mecanique sur le bord de l'enveloppe.
